Reasoning PYQs

BODMAS Table: 

Given equation: (9 Q 3) P 8 S (72 Q 12) P 7 R 15 P 3 = ?

Now, replacing the symbols as:

 

⇒ (9 ÷ 3) × 8 + (72 ÷ 12) × 7 − 15 × 3 = ?

⇒ 3 × 8 + 6 × 7 − 15 × 3 = ?

⇒ 24 + 42 − 15 × 3 = ?

⇒ 24 + 42 − 45 = ?

⇒ 66 − 45 = ?

⇒ 21

Hence, the correct answer is Option 1.

Given:

Rank from top = 8

Rank from bottom = 25

Total number of students = (Rank from top + Rank from bottom) − 1

= (8 + 25) − 1

= 33 − 1

= 32

Here, there are 32 students in the class.

Hence, the correct answer is "Option 3".

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

No one sits to the left of C.

Only four people sit between C and A.

Only three people sit to the right of G.

E sits to the immediate left of B.

F is not an immediate neighbour of G.

So, Total = 2

Hence, the correct answer is Option 1.

Given

Statements:

All pots are mats.

Some mats are hats.

All hats are cats.

The least possible Venn diagram for the given statement is:

Conclusions:

I. All cats are mats - Does not follow (Only some mats are hats and all hats are cats; this does not mean all cats are mats).

II. Some cats are pots - Does not follow (There is no definite relation between pots and cats).

So, neither conclusion I nor conclusion II follows.

Hence, the correct answer is Option 3.

Given: A, B, C, D, E and F are sitting around a circular table facing the centre.

A sits third to the right of F.

B sits second to the left of C.

D sits third to the right of C.

E sits to the immediate left of A.

 

Therefore, number of people between E and D = 1

Hence, the correct answer is Option 3.

The logic followed here is:

So, the next term = SSH

Hence, the correct answer is Option 3.

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

Now,

We need to count occurrences of 8 that are immediately preceded by an even number and immediately followed by an odd number.

So, the required condition is: Even Number – 8 – Odd Number

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

Total occurrences found = 4

Since 4 > 3, the answer is “Option 1”.

BODMAS Table: 

Given equation: 99 A 9 C 12 B 3 D 7 = ?

Now, replacing the symbols as:

 

⇒ 99 ÷ 9 + 12 × 3 − 7 = ?

⇒ 11 + 12 × 3 − 7 = ?

⇒ 11 + 36 − 7 = ?

⇒ 47 − 7 = ?

⇒ 40

Hence, the correct answer is Option 3.

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

Now,

We need to identify even digits that are immediately preceded by an even digit and immediately followed by an odd digit.

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

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

Total even digits satisfying the condition = 3

Hence, the correct answer is Option 3.

Given:

Arvind starts from Point K and drives 10 km towards the west.

He then takes a left turn and drives 8 km.

He again takes a left turn and drives 4 km.

He then takes a right turn and drives 4 km.

He then takes a left turn and drives 6 km.

Finally, he takes a left turn and drives 8 km and stops at Point Y.

Therefore, Point Y is 4 km towards the south of Point K.

Hence, the correct answer is Option 2.

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

Now,

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

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

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

Total odd numbers satisfying the condition = 4

Hence, the correct answer is "Option 2".

Family Chart:

Given: K + T & R x Z − V

It means: K is the son of T, T is the father of R, R is the wife of Z, Z is the brother of V.

Here, K is V’s brother

Hence, the correct answer is Option 3.

The logic followed here is:

Option 1) MQ – QX

Option 2) KO – PT

Option 3) FJ – KO

Option 4) BF – GK

Here, MQ – QX is odd from the given options because it does not follow the uniform +4, +1, +4 shift pattern.

Hence, the correct answer is "Option 1".

Given

Statements:

All peas are carrots.

All carrots are turnips.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some turnips are carrots - Follows (Since all carrots are turnips, there is definitely an overlap between turnips and carrots).

II. All peas are turnips - Follows (All peas are carrots and all carrots are turnips, so all peas are turnips).

So, both conclusions I and II follow.

Hence, the correct answer is Option 2.

The logic followed here is:

So, 'YZX 24' will replace the question mark in the given series.

Hence, the correct answer is "Option 2".

BODMAS Table: 

Given equation: 17 D 4 B 3 C 54 A 9 = ?

Now, if A stands for ‘÷’, B stands for ‘×’, C stands for ‘+’ and D stands for ‘−’, then:

17 D 4 B 3 C 54 A 9

⇒ 17 − 4 × 3 + 54 ÷ 9

⇒ 17 − 12 + 6

⇒ 5 + 6

⇒ 11

Hence, the correct answer is "Option 1".

Given

Statements:

All hats are mats.

All hats are cats.

All dogs are cats.

The least possible Venn diagram for the given statement is:

Conclusions:

I. All dogs are mats - Does not follow (There is no definite relation between dogs and mats).

II. Some cats are mats - Follows (Since all hats are both cats and mats, there is a definite common part between cats and mats).

So, only conclusion II follows.

Hence, the correct answer is Option 1.

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

Now,

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

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

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

Total odd numbers satisfying the condition = 4

Hence, the correct answer is "Option 2".

Given:

Total number of people = 47

Umesh’s position from right = 15^th

Ketan sits 19^th to the left of Umesh

Ketan’s position from right = 15 + 19 = 34^th

Ketan’s position from left = (Total + 1) − Position from right

= (47 + 1) − 34

= 48 − 34

= 14^th

Here, Ketan is 14^th from the left end of the line.

Hence, the correct answer is "Option 1".

The logic followed here is:

Given:

‘time heals wound’ → dj yk eb

‘let time reveal’ → fx ov yk

So, time → yk

Hence, the correct answer is Option 1.
