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: Some wings are toys. No toys are pens.

Conclusion (I): No pens are wings.

Conclusion (II): Some wings are not pens.

  1. AOption (a)

    Neither conclusion (I) nor (II) follows

  2. BOption (b)

    Only conclusion (II) follows

  3. COption (c)

    Both conclusions (I) and (II) follow

  4. DOption (d)

View answer & explanation

Correct answer

Answer: (b)B.

Only conclusion (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) No pens are wings - Doesn't follow

There is no direct relation between pens and wings may be it is possible but not definite. Hence, it is false)

(II) Some wings are not pens - Follow

(Some wings are toys that past of toys are not in pens. Non pens is toys. Hence, it is true)

Only conclusion (II) follows.

Hence, the correct answer is " Option 2"

  3. COption (c)

    16

  4. DOption (d)

    14

View answer & explanation

Correct answer

Answer: (c)C.

16

Why this answer is correct

The logic followed here is:

  • Total number of people in the row = 46
  • Position of Batul from the right end = 33rd
  • Position of Jaya from the left end = 31st

Position of Batul from the left = Total number of people − Position of Batul from the right + 1

= 46 − 33 + 1

= 14

Number of people between them = (Position of Jaya from the left − Position of Batul from the left) − 1

= 31 − 14 − 1

= 16

Hence, the correct answer is 'Option 3'.

Logic followed here is,

BODMAS Table:

LetterABCD
Mathematical Sign÷×+−

 

Substituting the signs for the letters, and applying BODMAS rule the equation becomes:

= 2 × 32 ÷ 1 − 1 + 45

 

= 2 × 32 − 1 + 45

= 64 + 45 − 1

= 109 − 1

= 108

The final value obtained is 108.

Hence, the correct answer is "option 4."
