Reasoning PYQs

Given: (Left) 9, 1, 8, 6, 9, 1, 8, 4, 8, 2, 6, 9, 7, 2, 6, 5, 9, 8, 4, 7, 1, 9, 1, 6, 9, 6, 5 (Right)

Now,

We need to identify even numbers that are preceded by an odd number and followed by an even number.

So, the required condition is: Odd Number – Even Number – Even Number

(Left) 9, 1, 8, 6, 9, 1, 8, 4, 8, 2, 6, 9, 7, 2, 6, 5, 9, 8, 4, 7, 1, 9, 1, 6, 9, 6, 5 (Right)

Total even numbers satisfying the condition = 4

Hence, the correct answer is "Option 3".

Given: Seven people A, B, C, D, E, F and G are sitting in a row facing north.

B is seated third from the right end.

G is third to the left of D.

E is seated to the right of B and at one of the ends.

Only two people are seated between F and E.

A does not sit at any of the extreme ends.

The extreme left end is position 1 → C

Hence, the correct answer is Option 1.

The logic followed here is:

thus, "868" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

The logic followed here is:

Given:

‘light reveals truth’ → rn ea kw

‘truth guides paths’ → ib rn xu

So, truth → rn

Hence, the correct answer is Option 1.

The logic followed here is:

For, BYRS → LIBC

Now, PMFG → ZWPQ

Now, applying the same logic for TQJK:

So, TQJK → DATU

Hence, the correct answer is Option 4.

The logic followed here is:

For, KNKM → LOLN

Now, ILIK → JMJL

Now, applying the same logic for OROQ:

So, OROQ → PSPR

Hence, the correct answer is Option 3.

Given: (Left) 3215674 (Right)

Now,

We need to modify each digit based on its parity and then identify the required position.

So, the required logic is:

Odd digit → Digit + 1

Even digit → Digit − 1

(Left) 3 2 1 5 6 7 4 (Right)

New number formed: 4 1 2 6 5 8 3

First digit from the right = 3

Hence, the correct answer is "Option 3".

BODMAS Table: 

Given equation: 42 A 6 D 5 B 3 C 18 = ?

Now, replacing the symbols as:

 

⇒ 42 ÷ 6 − 5 × 3 + 18 = ?

⇒ 7 − 5 × 3 + 18 = ?

⇒ 7 − 15 + 18 = ?

⇒ −8 + 18 = ?

⇒ 10

Hence, the correct answer is Option 4.

Given: (Left) 31264759 (Right)

Now,

We need to modify each digit based on its parity and then find the required positional sum.

So, the required logic is:

Even digit → Digit + 2

Odd digit → Digit − 1

(Left) 3 1 2 6 4 7 5 9 (Right)

New number formed: 2 0 4 8 6 6 4 8

Second digit from the left = 0

Third digit from the right = 6

Now, Sum = 0 + 6 = 6

Hence, the correct answer is "Option 4".

Family Chart:

Given: P + Q − R ÷ S × T

It means: P is the brother of Q, Q is the husband of R, R is the mother of S, S is the sister of T.

 

Here, P is related to T as Father’s brother

Hence, the correct answer is Option 3.

The logic followed here is:

So, 'JSI' will replace the question mark in the given series.

Hence, the correct answer is Option 1.

Given: Six people A, B, C, X, Y and Z are sitting around a circular table facing the centre of the table.

Z is sitting to the immediate left of A.

B is sitting second to the right of Z.

X is an immediate neighbour of both Y and C.

Y is not an immediate neighbour of Z.

 

So, B is immediately to the left of Y.

Therefore, the correct answer is Option 2.

The logic followed here is:

thus, "23" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

The logic followed here is:

thus, "-63" will replace the question mark in the given series.

Hence, the correct option is "Option 3".

The logic followed here is:

Logic: Third number = First number − Second number

92 - 6 - 86

⇒ 92 − 6 = 86

13 - 8 - 5

⇒ 13 − 8 = 5

Now, checking the options:

Option 1) 30 - 12 - 24

⇒ 30 − 12 = 18 (not 24)

Option 2) 50 - 20 - 30

⇒ 50 − 20 = 30

Option 3) 4 - 1 - 2

⇒ 4 − 1 = 3 (not 2)

Option 4) 12 - 5 - 6

⇒ 12 − 5 = 7 (not 6)

Hence, the correct answer is Option 2.

The logic followed here is:

So, 'POR 86' will replace the question mark in the given series.

Hence, the correct answer is "Option 2"

Given: (Left) 7 5 8 5 8 3 1 5 2 6 1 6 3 1 4 2 4 3 7 8 5 9 5 2 8 2 5 (Right)

Now,

We need even numbers which are preceded by an odd number and followed by an even number.

So, the required pattern is: Odd Number – Even Number – Even Number.

(Left) 7 5 8 5 8 3 1 5 2 6 1 6 3 1 4 2 4 3 7 8 5 9 5 2 8 2 5 (Right)

Total even numbers satisfying the condition = 3

Hence, the correct answer is "Option 4".

Given: A, B, C, D, N, O and P are sitting in a straight line facing north.

Only two people sit to the left of N.

Only three people sit between N and P.

O sits second to the right of N.

Only two people sit between O and D.

C sits at some place to the right of B but at some place to the left of A.

So, total people to the right of C = 3

Hence, the correct answer is "Option 4".

Given: (Left) 2 4 5 9 7 8 3 1 (Right)

Now,

We need to arrange the digits in ascending order and compare each position with the original arrangement to find how many remain unchanged.

So, the required logic is: Compare original order vs ascending order position-wise.

(Left) 2 4 5 9 7 8 3 1 (Right)

Now, arranging in ascending order: 1 2 3 4 5 7 8 9

No digit remains in the same position after sorting.

Therefore, the number of digits whose positions remain unchanged = 0

Hence, the correct answer is Option 4.

Given

Statements:

Some balls are hens.

All vans are hens.

The least possible Venn diagram for the given statements is:

Conclusions:

I. Some balls are vans – Does not follow (There is no necessary overlap between balls and vans in any case).

II. All hens are vans – Does not follow (Only vans are fully inside hens, not vice versa; hens may include elements outside vans).

So, neither conclusion I nor II follows.

Hence, the correct answer is Option 2.
