View answer & explanation

Correct answer

Answer: (c)C.

5

Why this answer is correct

Taking Dice position (1) and (2), as 3 and 6 are common;

The remaining number in Dice position (1) is 2.

The remaining number in Dice position (2) is 5.

So, 2 and 5 are opposite number pairs.

Hence, "5" is the correct answer.

View answer & explanation

Correct answer

Answer: (a)A.

Chintu

Why this answer is correct

Given: Five friends Aman, Chintu, Rahul, Gautam and Pintu are sitting in a row at different position.

  • Aman is sitting at the left end while Pintu is sitting second from the right end.

  • Only one friend sits between Pintu and Gautam. Which means Gautam will sit to the left of Pintu.

  • Rahul is not an immediate neighbor of Aman and Gautam. That means Rahul will sit to the immediate right of Pintu and Chintu will sit at the place left in between Gautam and Pintu.

So, the final arrangement will be as;

Hence, "Chintu" is sitting in the middle of the row.

In a certain code language,

 

‘A + B’ means ‘A is the father of B’,

 

‘A – B’ means ‘A is the brother of B’,

 

‘A × B’ means ‘A is the wife of B’, and

 

‘A ÷ B’ means ‘A is sister of B’.

 

If ‘P + Q × R + S ÷ T’, then how is P related to T?

  1. AOption (a)

P is the father of Q

Q is the wife of R

R is the father of S

S is the sister of T

Therefore, P will be the maternal grandfather of T.

Hence, the correct answer is "Option (2)".

Question 117

CSIR ASO 2024• General Intelligence, Reasoning and Mental Ability

Four letter-clusters have been given, out of which three are alike in some manner and one is different. Select the odd letter-cluster.

  1. AOption (a)

    KIO

  2. BOption (b)

  3. COption (c)

    WXA

  4. DOption (d)

    NOR

View answer & explanation

Correct answer

Answer: (a)A.

KIO

Why this answer is correct
