Left  1 3 4 5 6 7 8   Right 

  • second digit from the Left : 7
  • second digit from the right = 3
  • 3 + 7 = 10

Hence, the correct answer is "Option 4"

Question 605

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and Reasoning

In a certain code language,

A % B means ‘A is the father of B’,

A € B means ‘A is the wife of B’,

A = B means ‘A is the mother of B’, and

A ? B means ‘A is the daughter of B’.

Based on the above, how is B related to X if 'B = C ? O % P € X'?

  1. AOption (a)

    Sister

  2. BOption (b)

    Wife's mother

  3. COption (c)

Given: B = C ? O % P € X

 

Therefore, B is the mother of P, who is the wife of X → B is the Wife's mother of X.

Hence, the correct answer is "Option 2".

Question 606

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and Reasoning

Read the given statement(s) and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statement(s).

Statements: All kings are mountains. All mountains are arrows.

Conclusion (I): Some mountains are kings.

Conclusion (II): All kings are arrows.

  1. AOption (a)

    Only conclusion (I) follows

  2. BOption (b)

    Both conclusions (I) and (II) follow

  3. COption (c)

    Neither conclusion (I) nor (II) follows

  4. DOption (d)

    Only conclusion (II) follows

View answer & explanation

Correct answer

Answer: (b)B.

Both conclusions (I) and (II) follow

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) Some mountains are kings - Follows (All kings are mountains and Some kings are mountains. So, Some mountains are kings is true)

(II) All kings are arrows - Follows (All kings are mountains and all mountains are arrow. All kings are arrow. So it's true)

Both conclusions (I) and (II) follow.

Hence, the correct answer is "Option 2"
