Question 241

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

In a certain code language,

A x B means ‘A is the father of B’,

A ≠ B means ‘A is the son of B’,

A ÷ B means ‘A is the daughter of B’ and

A ₹ B means ‘A is the sister of B’.

Based on the above, how is C related to M if 'C ÷ D ₹ E ≠ L x M'?

  1. AOption (a)

    Mother's mother

  2. BOption (b)

Given : C ÷ D ₹ E ≠ L × M

  

Based on the tree, L is the father of E, D, and M. D is the sister of M, and C is the daughter of D. Therefore, C is the Sister's daughter of M.

Hence, the correct answer is 'Option 3'.

View answer & explanation

Correct answer

Answer: (b)B.

347

Why this answer is correct

The logic follows here, 

Logic: The difference between the consecutive terms in the series is a multiple of 17.

  • 92 + 17 = 109
  • 109 + 34 = 143
  • 143 + 51 = 194
  • 194 + 68 = 262
  • 262 + 85 = 347

Hence, the correct answer is "option 2".

Question 243

Question 246

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 beads are chairs.

All beads are monks.

Conclusions:

(I) Some chairs are monks.

(II) All monks are beads.

  1. AOption (a)

    Only conclusion (II) follows

  2. BOption (b)

    Neither conclusion (I) nor (II) follows

  3. COption (c)

    Both conclusions (I) and (II) follow

  4. DOption (d)

    Only conclusion (I) follows

View answer & explanation

Correct answer

Answer: (d)D.

Only conclusion (I) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

Conclusions:

(I) Some chairs are monks - Follows (All beads are chairs and all beads are monks. Some part of chairs is in part of monks)

(II) All monks are beads - Does not follow (All beads are monks. All monks are beads is may be possible but not definite)

Only conclusion (I) follows.

Hence, the correct answer is "Option 4".

  4. DOption (d)

    84

View answer & explanation

Correct answer

Answer: (b)B.

85

Why this answer is correct

BODMAS :

Given that:-

Symbol+-×÷
Meaning-×÷+

After replacing the signs and using BODMAS rule:

= 21 × 4 + 10 − 36 ÷ 4

= 21 × 4 + 10 − 9

= 84 + 10 − 9

= 94 − 9

The final value of the expression is 85.

Hence, the correct answer is "option 2"

Question 249

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

Based on the alphabetical order, three of the following four are alike in a certain way and thus form a group. Which is the one that does not belong to that group?

(Note: The odd one out is not based on the number of consonants/vowels or their position in the letter cluster.)
