Reasoning PYQs

BODMAS Rule:

According to the question, the signs are interchanged as follows:

Now, given the equation: 6 + (4 × 2) − 3 ÷ 1 = ?

After interchanging the specified signs, the new equation is:

6 − (4 ÷ 2) × 3 + 1 = ?

Perform operations according to BODMAS:

⇒ 6 − (4 ÷ 2) × 3 + 1

⇒ 6 − 2 × 3 + 1

⇒ 6 − 6 + 1

⇒ 1

Hence, the correct answer is "Option 4".

The logic follows here is:

The original directions are

 

The direction is rotating 135° anticlockwise. 

After changing direction.

South-East becomes North,

Similarly,

North-East becomes West after rotating 135° anticlockwise.

Hence, the correct answer is "Option 2".

Decoding symbols for Family Tree:

According to the given information Family Tree Representation

A is the brother of B. 

B is the mother of C. 

This makes A the brother of C's mother.

Thus, A is the Uncle of C.

Hence, the correct answer is "Option 2"

The logic followed here is:

Logic: (Number of letters in a word) × 4 = Number.

In the pair BRIGHT: 24,

(number of letters in BRIGHT) × 4

= 6 × 4

= 24

SMART has 5 letters → 5 × 4 = 20 ≠ 21 → logic does not follow

SHARP has 5 letters → 5 × 4 = 20 → logic follows

QUICK has 5 letters → 5 × 4 = 20 → logic follows

BRAINY has 6 letters → 6 × 4 = 24 → logic follows

Thus, SMART: 21 is the odd one out.

Hence, the correct answer is "Option 1".

Given:

Input: Volcano 37 19 Ash 50 Smoke 90 Dust 28

From the above input can be writing as steps as 

Step 1: Ash Volcano 37 19 50 Smoke Dust 28 50 90

Step 2: Ash Dust Volcano 37 19 Smoke 28 50 90

Step 3: Ash Dust Smoke Volcano 19 28 37 50 90

Step 4 (Final): Ash Dust Smoke Volcano 19 28 37 50 90

Thus, 37 19 28 50 90 will be the correct number sequence in step II.

Hence, the correct answer is "Option 4".

Given:

Red balls = 4

Blue balls = 6

Total balls = 4 + 6 = 10

Formula used:

Probability = Favourable outcomes ÷ Total outcomes

Calculations:

Favourable outcomes = 4

Total outcomes = 10

⇒ Probability = 4 ÷ 10 = 0.4

∴ Probability of drawing a red ball = 0.4.

The logic followed here is:

For AD to CF:

 

For EH:

 

Thus, the corresponding word for EH is GJ.

Hence, the correct answer is "Option 4".

The logic followed here is: 

Thus, the missing letter in the series is W.

Hence, the correct answer is "Option 1".

The logic followed here is:

FLOW = GMRZ 

WOLF is the opposite of FLOW,

Similarly,

ZRMG is the opposite of GMRZ.

Hence, the correct answer is "Option 2".

The logic follows here is -

23 - 3 = 8 - 3 = 5

3³ - 3 = 27 - 3 = 24

4³ - 3 = 64 - 3 = 61

5³ - 3 = 125 - 3 = 122

6³ - 3 = 216 - 3 = 213

Similarly,

7³ - 3 = 343 - 3 = 340.

Hence, the correct answer is "Option 2".

The logic followed here is:

Thus, the missing term in the series is LUIN.

Hence, the correct answer is "Option 1".

The logic followed in the given number pairs is:

Logic: 1^st + 22222 = 2^nd number.

Now,

For, 23145: 45367

⇒ 23145 + 22222 = 45367.

Applying the same logic for the second pair:

For, 41235: ?

⇒ 41235 + 22222 = 63457.

Thus, 41235: 63457.

Hence, the correct answer is "Option 2".

BODMAS Rule:

According to the question, the signs are interchanged as follows:

Now, given the equation: 15 − 4 ÷ 6 + 12 = ?

After interchanging the specified signs, the new equation is:

15 × 4 + 6 − 12 = ?

Perform operations according to BODMAS:

⇒ 15 × 4 + 6 − 12

⇒ 60 + 6 − 12

⇒ 66 − 12

⇒ 54

Hence, the correct answer is "Option 3".

Given:

While driving, you witness a minor fender bender in a parking lot. One car, which appears to be at fault, quickly drives away without stopping. The other car's driver is still in their vehicle, looking shaken and surveying the damage.

Option 2: Pull over safely, check on the driver of the damaged car, and offer to provide your contact information and what you witnessed ✅

The ethical and responsible action is to ensure the shaken driver is okay and provide accurate witness information if needed.

Hence, the correct answer is "Option 2".

Given:

Five students - P, Q, R, S, and T- are sitting in a circle facing the center. P is to the immediate right of Q. R is between P and S.

Thus, S is sitting to the immediate left of T.

Hence, the correct answer is "Option 3".

Given:

Number when divided by 5 leaves remainder = 3

Formula used:

If number = 5k + r, then square = (5k + r)² = 25k² + 10kr + r²

Remainder of square when ÷ 5 = remainder of r² ÷ 5

Calculations:

Number = 5k + 3

Square = (5k + 3)² = 25k² + 30k + 9

⇒ Square ÷ 5 leaves remainder of 9 ÷ 5 = 4

∴ Remainder = 4

GIven:

Statement:

The school has made computer training compulsory for all students.

Conclusion I: Computer knowledge is essential in the modern world.

This is a logical reason why the school might have made training compulsory.

It follows from the statement. ✅

Conclusion II: All students will become computer experts.

The statement only says training is compulsory, not that everyone will become an expert.

So this conclusion does not follow. ❌

This, Only Conclusion I follows.

Hence, the correct answer is "Option 1".

Given:

A faces D.

B is to the left of A.

F faces the person who is to the right of B.

C does not face F

Here we have 2 cases,

Case 1

Case 2

Thus, from both cases, B faces C.

Hence, the correct answer is "Option 2".

The logic followed here is:

Logic: All numbers are composite numbers except one.

11 is a prime number, and 22, 33, and 44 are composite numbers.

Hence, the correct answer is "Option 1".

The logic to find the odd one:

Logic: All the numbers, except one, are even numbers.

1. 579: This number is an odd number.

2. 468: This number is an even number.

3. 234: This number is an even number.

4. 936: This number is an even number.

Hence, the correct answer is "Option 1".
