Explanatory Answer
If you will simply read from our this guide,you will surely get full marks in this portion and you will never have to face difficulty regarding Analytical reasoning in aptitude tests or any other job or admission entry tests.This guide is in 5 simple parts.Simply read them all and you will be the master of reasoning.
Part 1
What is Analytical Reasoning?
In this part I have tried to cover two major things
regarding Analytical Reasoning Questions.
What is Analytical Reasoning?
How do you answer Analytical Reasoning Questions?
To be honest,with practice you can easily score 80% marks in this portion."Practice" has biggest role in this portion.
Analytical reason questions are like puzzle games where we are given some clues and we have to understand them in a way to answer other question related to those clues.
Let us solve an example to know what did i exactly mean.
Example 1
Problem
Statement
Three Musicians – D, E and F can play exactly one
instrument: The piano, The Flute, The Guitar – though not necessarily in the
same order.
D, whose sister is guitar
player does not play piano
F
is an only child.
Important Considerations while answering Analytical Reasoning Problems.
Approaches for Different Types of
Questions in Analytical Reasoning
There are mainly 4 types:
i) “What
must be true”? Or “What must not be false”?
ii) “What must not be true”? Or “What must
be false”?
iii) “Which can be true?” Or “Which could be true”? Or “Which may be
true”? Or “Which might be true”? Or “Which should be true”? Or “Which cannot be
false”? Or “Which could not be false”? Or “Which may not be false”? Or “Which
might not be false”? Or “Which should not be false?”
Is tara k questions main hum khud
ko confuse kar lete hain. Kis type main kaya approach use karni chahiye us k
liye hamain pehlay “MUST BE TRUE” or “MAY BE TRUE” ka difference samajna paray
ga. Q k “MUST BE TRUE” is not equal to “MAY BE TRUE”.
Special
Note: Analytical Reasoning Problems k
questions main “Can be, Could be, May be, Might
be, Shall be, Should be” in sab ka matlab aik he samja jata hai.
MUST BE TRUE

MAY BE TRUE

It is less ambiguous

It is more ambiguous

Ye wo exact answer hota hai jo de hoi
conditions ko fulfill karta
hai

Ye wo answer hota hai jo hum de hoi
statements say deduce kar
saktay hain

Is main hamain sirf de hoi information par he rely karna
parta hai

Is main hum apni valid assumptions b utilize kar saktay
hain

Is main hamain ye dhayan
rakhna parta hai k

Is main hamain ye dekhna
parta hai k jo

hum say exactly pocha kaya gaya hai sirf usi ka jawab dena
hota hai.

pocha gaya hai uski possibilities kitni ho sakti hain

Jo differences hum nay oper bayan
kiye hain un ka faraq samajnay k liye hum aik example discuss kar lete hain.
Suppose hamain aik aisi statement de gai hai k.
i) Jo insan stairs say girtay hain un ki
left tang toot jati hai. ii) Ali
aik insan hai aur wo staris say gir gaya hai.
Case – Must be ture:
Ab oper de gai statements ko agar
hum logically jorain to hamari pehli statement kehti hai k jo b insan stairs
say girta hai uski left tang tot jati hai aur Ali b insan hai aur wo stairs say
gir gaya hai to it “MUST BE TRUE” k uski left tang toot jaye ge.
Case – May be true:
Ab oper de gai statements say hum
ye result nahein nikaal saktay k Ali gira hai to uska bazo b toota hoga ya uski
qamar ki haddi b tooti ho ge. Q k ye chezain statement main kahi he nai gai. Ye
assumptions hum khud say laga rahay hain jo natural conditions main ho b sakti
hain aur nahein b. So this is the best explanation of “MAY BE TRUE”.
2) Process of Choice Elimination on the basis of
Initial Conditions
Sometimes jab kisi question main
koi extra conditions na de hon to hum elimination method k zariye say apnay
question ko asaani say solve kar saktay hain. Is main hum ye kartay hain k apni
har answering option ko apni conditions k sath compare kartay hain aur agar
kisi option main aik condition b violate ho jaye to us ko eliminate kar dete
hain aur is tara akhar main hamaray paas aik he option reh jati hai jis par
tamam conditions fulfill hoti hain aur wohi hamari answering option hoti
hai.
Isko
samajnay k liye hum aik choti c example discuss kar lete hain.
Problem Statement:
Six contestants, R, S, T, U, V, and W, are
to be placed first (highest) through sixth (lowest), though not necessarily in
that order, at the start of a singles PingPong challenge contest.
i)
R is placed above S.
ii)
V is placed above both T and U. iii) W is placed two places above T.
iv) R is placed either third or
fourth.
Question: Which of
the following is a possible initial placing from highest to lowest?
A) V,
T, W,R, U, S
B) W,
U, T,V,R,S
C) W,
S, T,R,V,V
D) V,
W, R, T, U, S
E) V,
W, T,R, U, S
Summarization of Initial Conditions
i)
R < S
ii) V
< (T & U) iii) W = T – 2 iv) R = 3 v 4
Elimination of Choices
Hum choices ki elimination k liye 2 methods
use kar saktay hain. In dono main say apko jo b approach better lagay ap wo use
kar lain ya phir agar ap ko is say better approach ka pata hai to ap wo b use
kar saktay hain. Q k ye methods hard and fast rules nahein hain. Dono
approaches nechay de gai hain.
a) Elimination
of Choices by using Answering Options
b) Elimination
of Choices by using Initial Conditions
Dono approaches apko aik jesi he lagain ge
but kuch log first main comfortable feel karain gay jab k kuch log second main.
So, I am explaining both of them.
a) Elimination
of Choices by using Answering Options
Is method main
hum bari bari kar k aik aik option pakrain gay aur us par initial conditions
apply karain gay. Jis option par aik b condition violate ho ge usay hum
eliminate kar dain gay aur end par sirf aik he option bachay ge jis par saray
rules satisfy hon gay aur wo hamara answer hoga.
Let us check option A first:
• Condition
no i is satisfied
• Condition
no ii is satisfied
•
Condition no iii is not satisfied
Ab hum condition
no iv ko check he nahein karain gay Q k jab aik b condition violate ho jaye to wo
answer ho he nahein sakta.
Let us check option B:
• Condition
no i is satisfied
•
Condition no ii is not satisfied
Ab hum condition
no iii and iv ko check he nahein karain gay Q k jab aik b condition violate ho
jaye to wo answer ho he nahein sakta.
Let us check option C:
•
Condition no i is not satisfied
So, option C be eliminate ho gai. Let us check option D:
• Condition
no i is satisfied
• Condition
no ii is satisfied
• Condition
no iii is satisfied
•
Condition no iv is also satisfied
Iska matlab hai k
hamara Answer option D he hai. Agar hum option E ko na b check karain to guzara
ho jaye ga lekin main apko suggest karon ga k ap tamam options zaror check
karain is say hamain ye pata chal jaye ga k hum nay kahein koi galti to nahein
ki.
Let us check option E:
• Condition
no i is satisfied
• Condition
no ii is satisfied
•
Condition no iii is not satisfied
So option E is
also eliminated. Now without any doubt our right answer after eliminating
process is option D.
b) Elimination
of Choices by using Initial Conditions
Is method main hum bari bari kar k
aik aik initial condition pakrain gay aur usay tamam options par apply karain
gay. Jo rule kisi b option par satisfy nahein hoga wo choice hum eliminate kar
dain gay. Is tara end par hamaray pas sirf aik he option bachay ge jis par
tamam rules apply hon gay aur wohi hamara answer hoga.
Let us check Condition i first:
• Satisfied
with Option A
• Satisfied
with Option B
• Not
Satisfied with Option C
• Satisfied
with Option D
•
Satisfied with Option E
Option C par
condition no i satisfy nahein hoti is liye option C yahen par eliminate ho jaye
ge aur further hum koi aur condition option C par check nahein karain gay.
Let us check Condition ii:
• Satisfied
with Option A
• Not
Satisfied with Option B
• Option
C is already eliminated so no need to check
• Satisfied
with Option D
•
Satisfied with Option E
Is test k baad Option B is also
eliminated.
Let us check Condition iii:
• Not
Satisfied with Option A
• Option
B is already eliminated so no need to check
• Option
C is already eliminated so no need to check
• Satisfied
with Option D
•
Not Satisfied with Option E
After checking
condition no iii, 2 more options A and E are eliminated. Ab sifr aik he option
bachi hai aur wo D hai lekin abi hum ye nahein keh saktay k D is our answer q k
abi aik condition baqi hai.
Let us check Condition iv:
• Option
A is already eliminated so no need to check
• Option
B is already eliminated so no need to check
• Option
C is already eliminated so no need to check
• Satisfied
with Option D
•
Option E is already eliminated so no need to
check
After testing all
initial conditions on Answering options, only D is left which satisfies all
given initial conditions. So, right answer is D.
I hope k aap ko
eliminating choices k through question ko solve karna samaj main aa gaya hoga.
Baqi dono approaches similar he hain aur apko jo b suitable lagay ap wo choose
kar lain.
Precautionary
Note: Ye zarori nahein k tamam question
elimination method say he hon. So, don’t
apply this method blindly on all questions.
3) Technical
Errors during interpretation of “If” statements
Jin statements
main word “If” use hota hai hum aksar unko interpretation main aik technical
error kar dete hain jo main nay nechay explain kiya hai. For example,
If P is selected, then Q must be
selected.
Is statement ka
matlab hai k agar P ko liya hai to Q ko lazmi lain gay. Lekin is ka ye har giz
matlab nahein hai k agar Q liya hai to P b lena paray ga. Yehe wo technical
mistake hai jo hum “If” ki statement walay question main kartay hain. So be
careful while dealing such statements.
4) Technical
Errors during interpretation of “If and only if” statements
Jin statements
main word “If and only if” use hota hai hum aksar unko interpretation main “If”
ki statement k sath mix kar dete hain hala k dono main aik bara clear
difference hai jo nechay de gai example main explain kiya gaya hai. For
example,
P is selected, if and only if Q is
selected.
Is statement ka
matlab hai k agar P ko liya hai to Q ko lazmi lain gay. Aur is ka ye b matlab
hai k agar Q liya hai to P b lena paray ga. Yehe basic difference hai “If”
statement main aur “If and only if” ki statement main. If and only if ko
sometime “Iff” say b zahar kiya jata hai.
Tabular form main difference nechay
diya gaya hai jis say apko key difference point zayada clear ho jayein gay.
If Statements

If and only If Statements

It is denoted by “If”

It is denoted by “If and
only if” or “Iff”

Symbolic representation is

Symbolic representation is
≡

Example: If P is selected,
then Q must be selected

Example: If and only if P
is selected, Q is also selected

Interpretation:
If P is selected then Q is also selected
But If Q is selected then
selection of P is not mandatory

Interpretation:
If P is selected then Q is also selected
If Q is selected then P is
also selected

5) Value Your Time
Ap sab nay 2 terms bohat zayada
suni hon ge.
• Effectiveness
• Efficiency
Hum farz kartay
hain k Ali aur Akbar nay GAT ka test diya. Test ka time 120 minutes tha. Ali
nay pora test 90 minute main solve kar liya jab k Akbar pora test diye hoye
time main solve nahein kar paya. Jab result aya to pata chala k Akbar k marks
Ali say zayada hain.
Oper wali statement parh kar hum 2
batain keh saktay hain.
1) Ali is more efficient than Akbar. Q k
Ali nay Akbar say pehlay pora paper solve kar liya 2) Akbar is more
effective than Ali. Q k Akbar nay paper main Ali say zayada marks liye.
Lekin dono main
say behtar kon hai. To answer hai k dono he nahein. Q k to be successful in any
field you have to effective as well as efficient. Same rule applies in GAT
test. Apko agar sara paper aata ho lekin aap usay within given time solve he na
kar sakain to uska koi faida nahein hai. So you have to value your time during
the test and you have to be very careful regarding those things which consume
time in Analytical Reasoning Question and normally termed as
• Point
Killers
•
Black Holes
Point Killers
Point killers is
tara k questions hotay hain jo apka waqt lazmi lete hain. Ap inko short cut
main solve nahein kar sakty. In main is tara k questions hotay hain
Agar P hoa to Q be ho ga
Agar Q hoa to R be ho ga
Agar R hoa to S nahein ho ga
Aisay questions ko
koshish karain k last par try karain ta k apka time baqi questions main b
distribute ho sakay
Black Holes
Science kehti hai k hamari universe main
bohat saray aisay Black Holes majood hain k jin main itni kashish hoti hai k
baray baray sitaray b us main gir kar kho jatay hain. Isi tara kuch
Analytical Reasoning Problems b Black Holes ki tara hotay hain k jab ap
unko start kartay hain to un main aisa kho jatay hain k apko time ka hosh he
nahein rehta aur apka kafi time waste ho jata hai. Agar koi is tara ka question
aa jaye to kabi kabaar Tukkay say b kaam chala lena chahiye aur time bacha lena
chahiye. Lekin agar ap k paas time hai to you should solve.Part 3
In part 3, main
nay ye discuss kiya hai
• Different
Categories of Analytical Reasoning Problems
•
Explanation of First two categories of
Analytical Reasoning Problems with the help of solved example problem
Ab baqi 2 parts
main b main different categories ka aik aik question with explanation solve
karon ga aur apko suggest karon ga k first 2 parts achi tara parh lain q k agar
apko first 2 parts clear hain to apko questions solve karnay main koi masla
nahein hoga.
DIFFERENT CATEGORIES OF
ANALYTICAL REASONING PROBLEMS
On the basis of
nature of questions, Analytical Reasoning problems can be divided into one of
the following categories.
1. Straight
Order
2. Scattered
Order
3. Suitable
Selections
4. Table
Seating Arrangements
a. Circular
Table Arrangements
b. Rectangular
Table Arrangements
5. Comparison
Problems
7. Matrix
Problems
8.
Relationship Problems
Ho sakta hai k
different books main ye method kisi aur name say available hon. Main nay wo
name use kiye hain jo us book main diye gaye hain jisko main follow kar raha
hon.
In GAT General
about 90% and sometimes 100% questions belong to first four categories. Jitnay
test main nay abi tak diye hain un main mostly 40% questions first category k
hotay thay. 30% second category k. 20% third category k aur 10% fourth category
k. Lekin iska ye har giz matlab nahein k baqi 4 categories ka kabi question
nahein aaya. So, prepare all methods but give more concentrattion on first four
categories as compared to last four categories. Now, I will explain first two
categories in this part.
1) Straight Order
The simplest and most commonly analytical reasoning questions
are straight order questions.
This kind of problems normally
starts with this kind of statements;
• Five
people standing in a line
• Twelve
people in a street in twelve houses Six
runners in a race etc
2) Scattered Order
A little bit tough as compared to
Straight Order problems but not toughest.
These kind of problems normally
start with
• There
are five chairs and four persons
• There
are ten people and six rooms
•
There are three people and five dishes etc . . .
In dono ka faraq ab ko main tabular
form main samjata hon
Straight Order

Scattered Order

Ye Analytical Problems ki sab say simple type hoti hai

Ye Analytical Problems ki thori c tough type hoti hai

Is main aam tor par tamam
individuals ko 1, 1 jaga mil jati hai. Is ko main nay nechay aik
example say clear kiya hai

Is main aam tor par tamam
individuals ko 1, 1 jaga nahein milti. Is ko main nay nechay aik
example say clear kiya hai

Example:
Aik street main 6 ghar hain aur un main total 6 log rehtay hain. Is main
zarori hai k har ghar main 1 he banda aaye. Aur koi b ghar khali na ho.

Example:
Aik street main 6 ghar hain aur un main total 10 log rehtay hain. Is main
zarori nahein k har ghar main 1 he banda aaye. Kisi main 1 say zayada b ho
saktay hain aur kisi main koi b nahein ho sakta.

Ye mostly symbols main summarize kar k solve ho jatay hain

In main aksar symbols k sath sath graphically b conditions
ko summarize karna parta hai

Mostly GAT main nearly 40% questions
Straight order k hotay
hain.

Mostly GAT main nearly 30% questions
Scattered order k hotay
hain.

Ye solve honay main sab say kam time lete hain

Ye solve honay main zayada
time lete hain.

Important Note: Analytical Problems chahay kisi b category k hon
agar hum wo tamam basic rules aur
precautions ko follow karain jo pehlay 2 parts main explain ki gai hain to ap
har type k questions ko easily solve kar
lain gay.
Now let us solve
one question of straight order. But before solving please make it sure k pehlay
2 parts apko mukamal clear hain.
Problem Statement – Straight Ordering:
In a school
function six students J,K,L,M,N and O are sitting in front row of six seats.
All six seats are numbered from 1 to 6. Only one person is sitting in one seat.
i)
J is sitting neither in seat 1 nor in seat 6.
ii)
N is not sitting next to L. iii) N is not sitting next to K. iv) O is sitting to the immediate
left of N.
Questions 1 to 6:
1 –
Which of the following seating arrangements, given in order from seat 1 to 6,
is acceptable?
A) L,
M, K, O, N, J
B) L,
J, M, O, N, K
C) L,
N,O, J, M, K
D) K,
J, L, O, M, N
E)
M, K, O, N, J, L
2
– All of the following seating arrangements,
given in order from 1 to 6, are acceptable EXCEPT:
A) M,
J, L, K, O, N
B) K,
J, O, N, M, L
C) K,
O, N, J, M, L
D) L,
O, N, J, K, M
E)
K, J, O, N, L, M
3 – If
L is in seat 1 and K is in seat 5, which of the following must be true?
A) J
is in seat 2
B) M
is in seat 3
C) N
is in seat 4
D) O
is in seat 4
E)
M is in seat 6
4 – If
M and O are in seats 2 and 3 respectively, which of the following must be true?
A) J
is in seat 5
B) K
is in seat 3
C) L
is in seat 1
D) L
is in seat 6
E)
N is in seat 5
5
– If K and L are separated by exactly three
seats, what is the maximum number of different arrangements in which the six
people could be seated?
A) 1
B) 2
C) 3
D) 4
E)
5
6
– If K is in seat 2, which of the following is a
complete and accurate listing of the seats which O could occupy?
A) 1
B) 3
C) 3
and 4
D) 1,
3 and 4
E)
3, 4 and 5
Solution
First of all we will
summarize our initial conditions either as per methods given in many books or
by our own developed signs.
i) J ≠ (1 v 6) ii) N ≠ L iii) N
≠ K iv) O —> N
Ab hum ye dekhain
gay k kaya hum initial conditions ko use kartay hoye further conclusions nikaal
saktay hain ya nahein.
G han hum yahan
say further conclusions nikaal saktay hain. Hum in conditions ko use kartay
hovay kai possible seating arrangements nikaal saktay hain lekin is kaam main
kafi zayada time lag jaye ga is liye filhaal hum further conclusions ko chor
kar agay move karain gay. Pehlay main sab questions k just answer don ga aur
aap b inko pehlay khud hal kar k dekhain k kaya aap k answer nechay diye gaye
answers k sath tally kartay hain ya nahein. Us k baad in answers ki main
explanation don ga.

Explanatory Answer
Is par hum wohi “Choice Elimination
Method” use karain gay.
Aur main isko “Elimination of
Choices by using Initial Conditions” solve karon ga.
Is method main hum
bari bari kar k aik aik initial condition pakrain gay aur usay tamam options
par apply karain gay. Jo rule kisi b option par satisfy nahein hoga wo choice
hum eliminate kar dain gay. Is tara end par hamaray pas sirf aik he option
bachay ge jis par tamam rules apply hon gay aur wohi hamara answer hoga. Let us
check Condition i:
• Not
Satisfied with Option A
• Satisfied
with Option B
• Satisfied
with Option C
• Satisfied
with Option D
•
Satisfied with Option E
Condition i k
mutabiq J 1^{st} ya 6^{th} seat par nahein ho sakta jab k
option A main J 6^{th} seat par hai. Is liye option A yaheen par
eliminate ho jaye ge
Let us check Condition ii:
• Option
A is already eliminated so no need to check
• Satisfied
with Option B
• Not
Satisfied with Option C
• Satisfied
with Option D
•
Satisfied with Option E
Condition ii main bara
clear likha hova hai k N, L k sath nahein bethay ga. Jab k option C main N aur
L ekathay bethay hoye hain so, option C is also eliminated.
Let us check Condition iii:
• Option
A is already eliminated so no need to check
• Not
Satisfied with Option B
• Option
C is already eliminated so no need to check
• Satisfied
with Option D
•
Satisfied with Option E
Condition iii main
likha hova hai k N aur K aik sath nahein bethain gay. Jab k option B main N aur
K ekathay bethay hoye hain so, option B is eliminated as well.
Let us check Condition iv:
• Option
A is already eliminated so no need to check
• Option
B is already eliminated so no need to check
• Option
C is already eliminated so no need to check
• Not
Satisfied with Option D
•
Satisfied with Option E
Condition iv kehti
hai k O hamesha N k foran left side par aaye ga jab k option D main aisa nahein
hai. So, after testing all initial conditions on Answering options, only E is
left which satisfies all given initial conditions. So, right answer is E.
Precautionary
Note: Agar choice elimination method k
baad aap k paas aik say zayada answering
options aa rahi hain to iska matlab hai k aap koi chez overlook kar gaye hain.
Aur agar koi b choice nahein aa rahi to
iska matlab hai k aap nay summarize kartay waqt koi condition galat interpret kar de hai. So, be careful.
Question – 2
All of the following seating
arrangements, given in order from 1 to 6, are acceptable EXCEPT:
A) M,
J, L, K, O, N
B) K,
J, O, N, M, L
C) K,
O, N, J, M, L
D) L,
O, N, J, K, M
E)
K, J, O, N, L, M
Explanatory Answer
Jab b aap question
ko parhain to ye zaror dekhain k akhar hum say pocha kaya gaya hai. Jesa k is
question main 5 arrangements de gai hain aur pocha gaya hai k kon c arrangement
thek nahein hai. To iska matlab ye hoa k hamari de gai conditions question main
de gai 4 options ko completely satisfy karain ge aur sirf aik option aisi ho ge
jis par koi na koi condition violate ho ge.
Again ye question
b “Choice Elimination Method” say ho jaye ga. Aur main isko b “Elimination of
Choices by using Initial Conditions” solve karon ga.
Let us check Condition i:
• Satisfied
with Option A
• Satisfied
with Option B
• Satisfied
with Option C
• Satisfied
with Option D
•
Satisfied with Option E
Kisi b option main
J na to 1^{st} position par hai aur na he 6^{th} par. Iska
matlab hai k pehli condition to sab he options ko satisfy kar rai hai so now we
will move towards another option.
Let us check Condition ii:
• Satisfied
with Option A
• Satisfied
with Option B
• Satisfied
with Option C
• Satisfied
with Option D
• Not
Satisfied with Option E
Option E main N
aur L ekathay bethay hain jo hamari condition ki violation hai. Question main
jo chez pochi gait hi hamain us ka answer mil gaya hai k Option E ki
arrangement acceptable nahein ho ge.
Agar aap chahain
to yaheen par ye question chor kar next question ki taraf move kar saktay hain
lekin main apko suggest karon ga k aap baqi dono conditions b lazmi check kar
lain ta k apko pata chal jaye k aap nay kahein koi galiti to nahein ki.
Let us check Condition iii:
• Satisfied

with Option A
• Satisfied
with Option B
• Satisfied
with Option C
• Satisfied
with Option D
•
Option E is already eliminated so no need to
check
Condition iii b
pehli 4 options par fully satisfied hai. Iska matlab k hum nay question main
koi galti nahein ki hai. Sirf option E aik aisi arrangement hai jis par
condition violate hoti hai so our Answe is Option E.
Question – 3
If L is in seat 1 and K is in seat

A) J
is in seat 2
B) M
is in seat 3
C) N
is in seat 4
D) O

E)
M is in seat 6
Explanatory Answer
Ye question tricky
hai q k is main 2 extra conditions de hoi hain. Aur main nay part 1 main
explain kiya tha k agar kisi question main koi extra condition ho to wo sirf
usi question k liye valid hoti hai aur agar extra condition kisi b initial
condition k sath contradict kar rahi ho to wo initial condition sirf is aik
question k liye invalid ho ge.
Chalain hum zara
dekh he lete hain k kaya koi initial condition extra condition k sath
contradict to nahein kar rahi
Initial Conditions
i) J ≠ (1 v 6) ii) N ≠ L iii) N
≠ K iv) O —> N
Extra Conditions given in
question number 3
a) L
= 1
b)
K = 5
Oper de gai
conditions say clear hai k koi b extra condition initial condition k sath
contradict nahein kar rahi. Is liye question 3 ko solve karnay k liye hum ye
sari 6 ki 6 conditions ko use karain gay.
Ab atay he sawal
ki taraf to hum say “MUST BE TRUE” pocha gaya hai. Is question ko solve karnay
k liye hamain dekhna paray ga k de gai conditions say kitnay possible seating
arrangements ban saktay hain. All possible seating arrangements with Initial
conditions and Extra conditions are given below,
According to extra conditions, L 1^{st}
seat par hoga aur K 5^{th} seat par hoga.
1
2 3 4 5 6
L K
Ab Initial
condition i ko dekhain to hamain ye zaror pata chalta hai k J 1^{st} ya
6^{th} par nahein aaye ga. To iska matlab J 2^{nd}, 3^{rd},
4^{th} ya 5^{th} par aaye ga. Lekin 5^{th} par to K aa
chukka hai to it means J ab 2^{nd}, 3^{rd} ya 4^{th}
par aaye ga lekin clear nahein hai k kis par aaye ga. Is liye waqt tor par hum
is condition ko chor kar agay move karain gay.
Ab initial
condition ii kehti hai N aur L ekathay nahein aa saktay isi tara initial
condition iii kehti hai k N aur K ekathay nahein aa saktay. Yahan say ye pata
chalta hai k hum N ko 2^{nd}, 4^{th} aur 6^{th} seat
par nahein bitha saktay to phir sirf 3^{rd} seat he bachti hai jahan N
beth sakta hai. So,
1

Option A: False, q k oper de gai arrangement main J to 4^{th}
par hai.
Option B: False, q k oper de gai arrangement main M to 6^{th}
seat par hai.
Option C: False, q k oper de gai arrangement main N to 3^{rd}
seat par hai.
Option D: False, q k oper de gai arrangement main O 2^{nd}
seat par hai.
Option E: True, M waqai oper de gai arrangement main 6^{th}
seat par hai.
So, our correct answer is option E.

An yahan par masla ye hai k answer kaya hai.
Hamain lagay ga k A b answer hai C b answer hai D b answer hai. Lekin answer to
sirf 1 he hona chahiye. It means we are overlooking something.
Lekin Kaya . . .
Zara question dobara parhain hum
say pocha gaya tha “MUST BE TRUE”
It means aisa
answer jo har possible arrangement main true ho. Option C aur D ka answer aik
arrangement main to true ho sakta hai magar dosri arrangement main galat hai.
Jab k Option A dono arrangement main true result day rahi hai,
So, our correct answer is option A.

b kiya tha. In part 4 main mazeed agli aik category ki aik example ko solve karon gay. So, is part main
main nay ye discuss kiya hai.
Suitable
Selection Analytical Problems with solved example
Part 5 main main
baqi tamam categories ko discuss karon ga. Lekin agay barhnay say pehlay main
apko batana chahon ga k Analytical Reasoning Problems ko solve karnay k liye jo
concepts main nay part 1 aur part 2 main explain kiye hain apki un par command
hona zarori hai. Q k baqi 3 parts main main nay har category k questions ko
solve kiya hai aur method main nay pehlay 2 parts main say he use kiye hain.
Aur agar apko pehlay 2 parts clear hain to believe me you can almost solve any
kind of Analytical Reasoning Problem, but, with one condition aur wo hai
PRACTICE. With practice aap is section main maximum score kar saktay hain.

3) Suitable Selections
Suitable Selection
category k questions main normally 2 ya 3 set diye hotay hain jin k darmayan
hamain de gai conditions k hisab say selection karni hoti hai. Yani hamain aik
baray group main say selection karni hoti hai. Normally in questions main is
tara ki statements hoti hain.
• To
form a committee of 6 people you will choose people from the group of teachers,
students and parents
• To
make a dish you have to choose ingredients from 2 combinations
•
To make a football team you have to choose
players from 3 different clubs etc . . .
Personally mujay is
category k question sab say zayada tricky lagtay hain q k jab aap nay aik
combination bananay k liye 3 groups main say selection karni hoti hai to aik
choti c mistake say apka sara question galat ho jata hai aur apka dher sara
time zaya ho jata hai. Aur ye sab say zayada time taking problems hotay hain.
Lekin iska ye matlab nahein k solve nahein hotay. Agar ap initial condition ko
thek tara interpret kar lete hain to beshak ye time consuming hai lekin phir b
solve lazmi ho jatay hain.
Important Note: Analytical Problems chahay kisi b category k hon agar hum wo tamam basic
rules aur precautions ko follow karain jo
pehlay 2 parts main explain ki gai hain to ap har type k questions ko easily solve kar lain gay.
Now let us solve one question of
Suitable Selection.
Problem Statement – Suitable
Selection:
The president of a
college wants to make a discipline committee by choosing members from a group
of 3 faculty members P, S and R, four administrative members T, U, V and W and
3 students X, Y and Z according to conditions given below,
i) The
committee will consist of seven members only ii) There must be at least as many faculty
members on the committee as there are students
iii) Number
of students may be zero iv) P
and Z cannot be selected together
v) T is selected, If and only if U is
selected vi) If V is selected then W
will also be selected
Questions 10 to 12:
10 –
Which of the following must be true of the committee?
A) Number
of students cannot be greater than number of Administrators
B) T
& W both cannot be selected together
C) All
three faculty members cannot be selected in committee
D) T
& U must be selected
E)
V & W must be selected
11 – If
exactly two faculty members and exactly two students are included in committee
then which of the following must be true?
A) Z
in not selected
B) W
is selected
C) X
is selected
D) Y
is selected E) S is selected
12 – If
both V and W are selected for the committee, then which of the following must
be true?
A) Neither
X nor W is selected
B) Neither
X nor Y is selected
C) Both
X and T are selected
D) Both
Y and U are selected
E)
V & X or V & Y is selected
Solution
Main nay kaha tha
na k ye question bohat tricky hotay hain a bap nay b dekh liya hoga k 3
different groups day diye hain aur un main say hum nay suitable selection karni
hai. Ab zara pehlay hum initial conditions ko summarize kar lete hain
i)
No. of Members in Committee = 7
Teno groups ko
members ko mila kar total 10 members bantay hain jin main say pehli condition k
mutabiq hum sirf 7 log select kar saktay hain.
ii)
No. of Faculty Member ≥ No. of Students
Yani committee
main kam az kam itnay faculty member lazmi hon gay jitney student hai. Aur
Faculty member student say zayada b ho saktay hain. iii) No. of students ≥ 0
Is condition main
kaha gaya tha k student MAY BE ZERO. Yani zero ho saktay hain lekin iska ye
hargiz matlab nahein hai k zero he hon gay.
iv)
P ≠ Z
Yani P aur Z ekathay kaam nahein
kar saktay
v)
T ≡ U
If and only if ka
matlab hai k agar T hoga to U b hoga aur agar U hoga to T be hoga. Yani dono
ekathay he select hon gay
vi)
V ⊃ W
Ab main zara in
tamam initial conditions ki representation ko aik he jaga par ekatha likh deta
hon
i) No. of Members in Committee
= 7 ii) No. of Faculty
Member ≥ No. of Students iii) No.
of students ≥ 0 iv) P ≠ Z
v) T ≡ U vi) V
⊃ W
Ab hum ye dekhain
gay k kaya hum initial conditions ko use kartay hoye further conclusions nikaal
saktay hain ya nahein. Kher muj say to koi further conclusion nahein nikla. But
again it doesn’t mean k koi b nahein nikal saktay . . .

Explanatory Answer
MUST BE TRUE wala question so you
know very well that what we are looking for.
Option A: True, q k as per initial
condition no iv, P aur Z kabi ekathay nahein aa saktay aur phir as per initial
condition no. ii, committee main kam az kam itnay faculty members to honay
chahiye jitney students hon. Is logic say committee main maximum 2 student
select kiye ja saktay hain. Aur 2 students hain to phir faculty member kam az
kam aur zayada say zayada 3 hon gay. Aur q k total group members 7 hain to
administrators b kam say kam 2 aur zayada say zayada 3 hon gay. To ye confirm
hai k number of student zayda ho he nahein saktay number of administrative say.
Option B: May be, T aur W ki koi
initial condition nahein de gai hai so ye dono ho b saktay hain aur nahein b
Option C: May be, Again 3 faculty b ho saktay hain aur 2 say b
group ban sakta hai.
Option D: False, Dono ko select kiye bagair b group create ho sakta

Dono types k questions hum unhi basics ko follow kar k solve karain gay jo hum part 1 aur part 2 main discuss kar chukhay hain. Is type k questions mostly is tara start hotay hain.
• Six people sitting around a circular table
• 8 people sitting around a rectangle table etc
Ab zara hum dono types k baray main kuch faraq dekh lete hain.
Rectangle Table Problems Circular Table Problems
Ye Circular Table Problems ki nisbat easy hotay hain Ye Rectangle Table Problems ki nisbat tough hotay hain
Is may seating arrangement ka starting point easily define kiya ja sakta hai. K left side say karain ya right side say Is main seating arrangement ka starting point define nahein kiya ja sakta q k table round hota hai to jahan say marzi start kar saktay hain
Easy to make arrangement q k hum aik table k 4 protions kar k dekh saktay hain k kon kahan aaye ga Difficult to make arrangement q k hum table ko divide nahein kar saktay
Example: 8 Peoples seating around a rectangle table . . . Example: 6 Peoples seating around a circular table . . .
Important Note: Analytical Problems chahay kisi b category k hon agar hum wo tamam basic rules aur precautions ko follow karain jo pehlay 2 parts main explain ki gai hain to ap har type k questions ko easily solve kar lain gay.

In the network there are twoway roads connecting each of the following pairs of points: A with B, A with C, A with E, B with F, C with G, E with F, and F with G. There are also oneway roads going from B to D, from C to B, and from D to C. There are no other roads in the network, and the roads in the network do not intersect. To make a trip involving pickups and deliveries, the boy always takes a route that for the whole trip passes through the fewest of the points A through G, counting a point twice if he boy passes through it twice. The boy's house is at point C. Aids can be picked up at a General Store at point A, a garmenting store at point E, and a bakery at point D, Deliveries can be made as needed to a tutoring center at point B, a distribution center at point F, and a supermarket at point G.

Is k solution k liye hamain Family Tree banana paray ga us ki madad say hamara question palak jhapaktay solve ho jaye ga.
Male k liye ka sign use kiya gaya hai
Female k liye ka sign use kiya gaya hai
Mian aur BV k relation double line ‘=’ say zahir kiya gaya hai
Mian aur BV ki aulad ko Down line say zahar kiya gaya hai
Bhai aur Behan k liye dotted signle line      ko use kiya gaya hai
Ab zara hum question ki statement ko parhtay hoye family tree develop kar lete hain.
Bira, an only child, is married and she and her husband have two children, Nasir and Samina.
Yaha tak hamain ye pata chal raha hai k Bira apnay maa baap ki akloti beti hai aur us k 2 bachay hain Nasir aur Samina
Jab b family tree banana ho to ye zarori nahein hota k sirf un ko show kiya jaye jin j name hain. Hamain puri Husband Wife ki theory ko follow karna parta hai. Jis ka pata ho k kon hai usay label kar dete hain aur agar kisi ka na pata ho to usay blank chor dete hain.
Ab statement thori mazeed parh kar dekhtay hain.
Nasir is Parveen’s nephew by blood and Vicky’s grandson
Ab yahan say ye pata chalta hai k Parveen Nasir ki Phupho yani Bira k husband ki behan hai aur Vicky Nasir ka Dada hai ya Nana abi ye clear nahein hai. Lekin sawal ye paida hota hai k ye kese pata chala k Parveen Nasir ki phupho hai Khala nahein to jawab bara simple hai k Bira to apnay maa baap ki akloti beti hai us ka koi behan bhai nahein hai.
Ab hum baqi information lay kar apna family tree complete kartay hain.
Vicky and his wife had only two children Fahad and his sister plus four grandchildren (Two boys and Two girls). Warda is Samina’s grandmother
Ab yahan say ye sabat ho gaya k gaya k Vicky Nasir ka dada hai q k Bira to akloti hai jab k Vicky k 2 bachay hain Parveen aur Fahad. Iska ye b matlab hai k Fahad Bira ka husband hai.
Aik aur chez clear hoti hai k Vicky k 2 potay 2 potiyan hain. 2 to Fahad k through hain iska matlab baqi 2 Parveen k through hain.
Lekin aik chez abi b unclear hai wo hai Warda. Us k baray main hum ye clear nahein keh saktay k wo Samina ki Dadi hai ya Nani.
