Reasoning PYQs

Given

Statements:

All torches are keys.

All keys are locks.

Some locks are batteries.

The least possible Venn diagram for the given statements is:

Conclusions:

I. All torches are locks – Follows (Since all torches are keys and all keys are locks, all torches must be locks).

II. Some batteries are torches – Does not follow (Although some locks are batteries and torches are inside locks, there is no definite overlap between batteries and torches).

So, only conclusion I follows.

Hence, the correct answer is Option 4.

The logic followed here is:

For, YAC → GIK

Now, QSU → YAC

Now, checking the options:

Option 1) JLN → QTU

Option 2) JKL → RTV

Option 3) JLN → RTV

Option 4) JKL → QSU

Hence, the correct answer is Option 3.

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

Now,

We need odd digits which are preceded by an even digit and followed by an odd digit.

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

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

Total odd digits satisfying the condition = 3

Hence, the correct answer is "Option 3".

The logic followed here is:

Logic: Add the reverse positional values of all the letters (A = 26, B = 25, ..., Z = 1) and then add 3 to the total.

For, QOEX → 50

⇒ Q = 10, O = 12, E = 22, X = 3

⇒ 10 + 12 + 22 + 3 = 47

⇒ 47 + 3 = 50

For, WPIU → 42

⇒ W = 4, P = 11, I = 18, U = 6

⇒ 4 + 11 + 18 + 6 = 39

⇒ 39 + 3 = 42

Now, applying the same pattern to SANR:

⇒ S = 8, A = 26, N = 13, R = 9

⇒ 8 + 26 + 13 + 9 = 56

⇒ 56 + 3 = 59

Hence, the correct answer is Option 4.

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

Only two people sit to the left of F.

Only one person sits between D and E.

F sits to the immediate left of D.

A sits to the immediate right of C.

B sits third to the right of A.

Now, C is at the extreme left position.

Hence, the correct answer is Option 2.

Given: (Left) 582, 128, 563, 183, 592 (Right)

Now, We need to identify the highest and lowest numbers from the given sequence, then extract the required digits and find their sum.

(Left) 582, 128, 563, 183, 592 (Right)

Now,

Highest number = 592

Lowest number = 128

Third digit of highest number = 2

Second digit of lowest number = 2

Now, Sum = 2 + 2 = 4

Therefore, the resultant is Option 2.

Given: Prakash is 3^rd from the left. Charan is 11^th from the right. Total students = 18.

Charan’s position from the left = N – position from right + 1

= 18 – 11 + 1

= 8^th from the left

Prakash’s position from the left = 3^rd

Now, number of people between them = |8 − 3| − 1

= 5 − 1

= 4

Here, there are 4 people standing between Charan and Prakash.

Hence, the correct answer is "Option 1".

BODMAS Table: 

Given equation: (90 Q 15) P 8 R 7 P 4 S (12 P 3) Q 2 = ?

Now, replacing the symbols as:

 

⇒ (90 ÷ 15) × 8 − 7 × 4 + (12 × 3) ÷ 2 = ?

⇒ 6 × 8 − 7 × 4 + 36 ÷ 2 = ?

⇒ 48 − 28 + 18 = ?

⇒ 20 + 18 = ?

⇒ 38

Hence, the correct answer is Option 1.

The logic followed here is:

Given:

‘ride those horses’ → dq fn ta

‘horses run wild’ → vy dq si

So, horses → dq

Hence, the correct answer is Option 1.

Family Chart:

Decoding the Symbols:

Given: K x T − R + Z & V

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

Here, K is related to V as Brother’s wife

Hence, the correct answer is "Option 4".

The logic followed here is:

thus, "342" will replace the question mark in the given series.

Hence, the correct option is "Option 2"

The logic followed here is:

For, PAST → PSTA → ASPT

Now, QUAD → QADU → UAQD

Now, checking the options:

Option 1) VAIN → VIAN → NIAV

Option 2) IDEA → IEAD → DEIA

Option 3) USER → UERS → SURE

Option 4) TIDE → ITDE → IDET

Hence, the correct answer is Option 2.

The logic followed here is:

Option 1) QPS

Option 2) HGI

Option 3) YXZ

Option 4) VUW

Here, QPS is odd from the given options because it follows −1, +3 instead of −1, +2.

Hence, the correct answer is "Option 1".

Given:

Minute hand is pointing North (12 o’clock)

Hour hand is pointing East (3 o’clock)

So, the initial time is 3:00

After 2 hours 30 minutes:

New time = 3:00 + 2:30 = 5:30

At 5:30, the minute hand points at 6

Minute hand at 6 → South

Here, the minute hand points towards South.

Hence, the correct answer is Option 4.

Given:

Mr. Pasto starts from Point A and drives 11 km North.

He turns left → 7 km West.

He turns left → 13 km South.

He turns left → 21 km East.

He takes a final left → 2 km North.

 

So, To reach Point A again, he must travel 14 km West.

Hence, the correct answer is Option 1.

Given: (Left) 426 125 357 489 627 (Right)

Now,

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

(Left) 426 125 357 489 627 (Right)

Now arranging in ascending order: 125 357 426 489 627

Number of unchanged positions = 2

Hence, the correct answer is "Option 4".

The logic followed here is:

Option 1) FI – DH

Option 2) DG – BF

Option 3) HK – FI

Option 4) JM – HL

Here, HK – FI is odd from the given options because it follows (−2, −2) instead of (−2, −1).

Hence, the correct answer is "Option 3".

Given: Six boxes A, B, C, D, P, Q and R are arranged from top to bottom (Position 7 to Position 1).

Q is at the topmost position.

There are 3 boxes between Q and D, so D is at position 3.

B is immediately above D, so B is at position 4.

C is placed such that only 1 box is between C and B, so C is at position 6.

There are 4 boxes between C and R, so R is at position 1.

A is above P, so A is at position 5 and P is at position 2.

Here, the box kept second below A is D.

Hence, the correct answer is Option 1.

Given: (Left) 7435681 (Right)

Now,

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

So, the required logic is:

Odd digit → Digit + 1

Even digit → Digit − 2

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

New number formed: 8 2 4 6 4 6 2

Third digit from the left = 4

Third digit from the right = 4

Now, Sum = 4 + 4 = 8

Hence, the correct answer is "Option 1".

The logic followed here is:

For, STW → ZAD

Now, PQT → WXA

Now, checking the options:

Option 1) TTV → ZAD

Option 2) TUX → ZBD

Option 3) TTV → ABE

Option 4) TUX → ABE

Hence, the correct answer is Option 4.
