Reasoning PYQs

Given:

We need to find which number is NOT a multiple of 3.

Now, A number is divisible by 3 if the sum of its digits is divisible by 3.

Now check each option:

369 → 3 + 6 + 9 = 18 (Divisible by 3) 

372 → 3 + 7 + 2 = 12 (Divisible by 3) 

375 → 3 + 7 + 5 = 15 (Divisible by 3) 

377 → 3 + 7 + 7 = 17 (Not divisible by 3) 

Hence, the correct answer is Option 4.

The logic followed here is:

Option 1) India → Located in Asia.

Option 2) China → Located in Asia.

Option 3) Nepal → Located in Asia.

Option 4) Brazil → Located in South America.

Hence, the correct answer is "Option 4".

The logic followed here is:

Option 1) Narendra Modi → Politician

Option 2) Rahul Gandhi → Politician

Option 3) Amit Shah → Politician

Option 4) Mahendra Singh Dhoni → Cricketer / Sports personality

Hence, the correct answer is "Option 4".

Family Chart:

Given:

M is the sister of N.

N is the father of R.

T is the mother of M.

 

So, T is the Grandmother of R.

Hence, the correct answer is "Option 2".

Family Chart:

Given:

T is the brother of R.

R is the son of M.

 

So, T is the Son of M.

Hence, the correct answer is "Option 2".

The logic followed here is:

We calculate the position sum of each group of letters (A = 1, B = 2, … Z = 26).

Option 1) P, Q, R → 16 + 17 + 18 = 51

Option 2) C, D, Y → 3 + 4 + 25 = 32

Option 3) A, B, Z → 1 + 2 + 26 = 29 

Option 4) M, N, O → 13 + 14 + 15 = 42

Hence, the correct answer is "Option 3".

Given: Six persons P, Q, R, S, T, U were born in six different years:

1946, 1958, 1963, 1971, 1994, 2006

Age is calculated with respect to 2019.

Birth Year → Age in 2019

 

The sum of the ages of S and P is 86.

Possible pairs giving 86:

73 + 13 = 86

So, S and P are 73 and 13.

S was born in an even-numbered year and is older than P.

Even-numbered year from (1946, 1958, 1963, 1971, 1994, 2006) → 1946, 1958, 1994, 2006

Among pair (73, 13):

73 → 1946 (even year)

13 → 2006

So, S → 1946

P → 2006

The sum of the ages of P and R is 81.

P = 13

So, R = 81 − 13

= 68  (No such age available)

Now, 61 + 25 = 86

So, S and P are 61 and 25.

S older than P and born in even year.

61 → 1958 (even year)

25 → 1994 (even year)

Since, S older than P →

S = 1958

P = 1994

Here, The sum of ages of P and R is 81.

P = 25

R = 81 − 25

= 56

56 → 1963

Conditions satisfied.

Hence, P was born in 1994.

Hence, the correct answer is "Option 2".

Decoding the Symbols:

 

Given: R is a brother of P.

 

So, R * Q & P is true.

Hence, the correct answer is "Option 3"$.

Given Statements:

All pens are blue things.

Some blue things are plastic.

No plastic is recyclable.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some pens are plastic – False (Because, although some Blue things are Plastic and all Pens are Blue things, there is no definite relation given between Pens and Plastic. It is only possible, not definite.)

II. Some blue things are not recyclable – True (Because, some Blue things are Plastic and no Plastic is Recyclable. Therefore, those Blue things which are Plastic are definitely not Recyclable.)

So, Only conclusion II follows.

Hence, the correct answer is "Option 2".

The logic followed here is:

Logic: Each letter is shifted one position backward in the English alphabet.

Given, BRAIN → A Q Z H M

Now, H E A R T:

So, HEART → G D Z Q S

Hence, the correct answer is "Option 1".

The logic followed here is:

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

Hence, the correct answer is "Option 1".

Given word: ANAESTHETIZED

Gemini sai 

Let's check all the options:

(1) Atomize ⇒ It can't be formed as it requires O and M.

(2) Anemia ⇒ It can't be formed as it requires M.

(3) Dentist ⇒ It can be formed. It uses D, E, N, T, I, S, T which are all present in ANAESTHETIZED.

(4) Anzio ⇒ It can't be formed as it requires O.

So, the answer is "Dentist". 

Hence, the correct answer is Option 3.

The logic followed here is:

So, 'DFI' is different from the rest in the given series.

Hence, the correct answer is "Option 3".

The logic followed here is:

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

Hence, the correct answer is "Option 1".

The logic followed here is:

thus, "76" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

The logic followed here is:

Logic: (First number × Second number × First number)

Check:

2 & 2 → 2 × 2 × 2 = 8 (but given 12)

3 & 3 → 3 × 3 × 3 = 27 

So adjust pattern:

Observe:

2 → 12 = (2^3 + 4)

3 → 27 = (3^3)

Better pattern:

(n × n × (n + 1))

Check:

2 → 2 × 2 × 3 = 12 

3 → 3 × 3 × 4 = 36 

Try:

(n^3) + something inconsistent → reject

Now look simpler:

2 & 2 = 12 → 2 × 6

3 & 3 = 27 → 3 × 9

Pattern:

Multiply by 3n

⇒ (n × 3n = 3n^2)

Check:

2 → 3×4 = 12 ✔

3 → 3×9 = 27 ✔

So:

4 → 3 × 16 = 48

Final Answer: 48

Hence, the correct answer is "Option 4".

The logic followed here is:

thus, "65" will replace the question mark in the given series.

Hence, the correct option is "Option 2".

Given:

Cost Price (CP) of 15 articles = Selling Price (SP) of 12 articles

According to Question:

Let CP of 1 article = ₹1

So, CP of 15 articles = ₹15

Therefore, SP of 12 articles = ₹15

SP of 1 article = 15 / 12

= ₹1.25

Profit per article = SP − CP

= 1.25 − 1

= ₹0.25

Profit % = (Profit / CP) × 100

= (0.25 / 1) × 100

= 25%

Hence, the correct answer is Option 1.

The logic followed here is:

Given, GARDEN → H B S F O O

Now, H B S F O O:

So, HBSFOO → ICTHYP

Hence, the correct answer is "Option 1".

Given:

Statement:

Ramesh receives higher grades than Suresh but lower grades than Mahesh.

Suresh’s marks = 70

This means: Mahesh > Ramesh > Suresh (70)

Now, check the options:

Option 1) Ramesh's marks are 65, Mahesh's marks are 70 – Does not follow (Because, Ramesh must have more than 70, but here he has 65.)

Option 2) Ramesh's marks are 75, Mahesh's marks are 80 – Follows (Because, 80 > 75 > 70, which satisfies Mahesh > Ramesh > Suresh.)

Option 3) Ramesh's marks are 60, Mahesh's marks are 70 – Does not follow (Because, Ramesh must score more than 70, but here he has 60.)

Option 4) Ramesh's marks are 85, Mahesh's marks are 75 – Does not follow (Because, Ramesh must score less than Mahesh, but here 85 > 75.)

So, Only option 2 satisfies the condition.

Hence, the correct answer is "Option 2".
