Reasoning PYQs

The logic followed here is:

Logic: To find A:C, make the common term B equal in both ratios and then compare A and C.

Given: A:B = 2:3 and B:C = 4:5

Here, Make B equal → LCM of 3 and 4 = 12

A:B = 2:3 → multiply both by 4 → 8:12

B:C = 4:5 → multiply both by 3 → 12:15

Now A:C = 8:15

Hence, the correct answer is "Option 1".

The logic followed here is:

Logic: Each letter in the word is shifted forward by 1 in the alphabet.

Given: COMPUTER → DPNQVUFS

Applying the same to LAPTOP:

So, LAPTOP → MBQQPQ

Hence, the correct answer is "Option 1".

The logic followed here is:

Logic: Total amount ÷ Number of people = Share per person

Given: Total = Rs. 640, originally 8 people, now 2 back out → 6 people remain

New share per person = 640 ÷ 6 = 106.67

Hence, the correct answer is Option 1.

The logic followed here is:

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

Hence, the correct option is "Option 2".

The logic followed here is:

thus, "77" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

The logic followed here is:

Logic: The code of each letter = 27 − position of the letter in the alphabet (A=1, B=2, … Z=26).

C → 3 → 27 − 3 = 24

A → 1 → 27 − 1 = 26

T → 20 → 27 − 20 = 7

So, CAT → 24, 26, 7

Hence, the correct answer is "Option 1".

The address given is:

D-14, New Friends Colony, South Delhi, Delhi - 110065

Let's match this address with the given options one by one to figure out which one is exactly the same.

So, the address that is exactly the same as the given address is in option (3).

Hence, the correct option is "option (3)".

Given: Seminars were held daily from 11^th to 18^th February.

Patna’s seminar was on 12^th February.

Two days after 12^th February is 14^th February.

On 14^th February, the seminar was held in Rourkela.

Hence, the correct answer is Option 2.

The logic followed here is:

Logic: Result = Larger number − 2 × Smaller number

Check:

11 − 3 → 11 − 2×3 = 11 − 6 = 5

14 − 5 → 14 − 2×5 = 14 − 10 = 4

Apply to 18 − 6:

18 − 2×6 = 18 − 12 = 6

Hence, the correct answer is Option 2.

The logic followed here is:

Logic: The symbol “#” represents addition.

4 # 3 → 4 + 3 = 7

6 # 2 → 6 + 2 = 8

Apply to 5 # 7 → 5 + 7 = 12

Hence, the correct answer is Option 1.

The logic followed here is:

Logic: The operation “#” is defined as # = (first number × second number) + second number

Check:

4 # 2 → 4 × 2 + 2 = 8 + 2 = 10

5 # 3 → 5 × 3 + 3 = 15 + 3 = 18

6 # 4 → 6 × 4 + 4 = 24 + 4 = 28

Apply to 7 # 5 → 7 × 5 + 5 = 35 + 5 = 40

Hence, the correct answer is Option 3.

The logic is based on the continent in which the country is located.

Option 1: Germany – A country in Europe.

Option 2: Kenya – A country in Africa.

Option 3: France – A country in Europe.

Option 4: Italy – A country in Europe.

Among these, Kenya is the only country that is not in Europe.

Hence, the odd one out is Option 2.

Family Chart:

Given:

A is the daughter of B.

B is the daughter of C.

Therefore, A is the granddaughter of C.

Hence, the correct answer is "Option 1".

The given proportion is: 11 : 1452 :: 12 : ?

Step 1: Look for a pattern

Notice that 1452 can be obtained by multiplying 11 × 12 × 11.

11 × 12 = 132

132 × 11 = 1452

So, the pattern is: n × (n + 1) × n.

Apply the same rule for 12

12 × 13 = 156

156 × 12 = 1872

Thus, the missing number is 1872.

Hence, the correct option is "Option 1".

Given Statements:

All squares are rectangles.

All rectangles are quadrilaterals.

The least possible Venn diagram for the given statements is:

Conclusions:

I. All squares are quadrilaterals – True (Squares are inside Rectangles, and Rectangles are inside Quadrilaterals.)

II. Some quadrilaterals are rectangles – True (Rectangles are part of Quadrilaterals.)

Hence, both conclusions I and II follow.

The correct answer is "Option 3".

Given Statements:

No woman is lazy.

Some men are lazy.

The least possible Venn diagram for the given statements is:

Conclusions:

I. No man is a woman – False (There is no information about men and women being mutually exclusive.)

II. Some lazy people are men – True (Some men are lazy, so some lazy people are definitely men.)

Hence, only conclusion II follows.

The correct answer is "Option 2".

Given words: apron, apple, aptitude, apply

Logic: Arrange the words according to dictionary (alphabetical) order.

Compare the letters:

All words start with “ap”.

Third letter comparison:

apple → p

apply → p

apron → r

aptitude → t

So, words with p come first → apple, apply

Now compare apple and apply:

apple

apply

Since e comes before y in the alphabet, apple comes first.

Hence, the correct answer is Option 2.

The logic is based on the pattern of letters and numbers.

A5

A (1) → 1 + 4 = 5 

C7

C (3) → 3 + 4 = 7 

E9

E (5) → 5 + 4 = 9 

G11

G (7) → 7 + 4 = 11 

I10

I (9) → 9 + 4 = 13 ≠ 10 

Thus, I10 does not follow the pattern.

Hence, the odd one out is Option 1.

The logic followed here is:

thus, "33" will replace the question mark in the given series.

Hence, the correct option is "Option 4".

The logic followed here is:

Thus, 13 is the incorrect number in the series.

Hence, the correct answer is Option 3.
