View answer & explanation

Correct answer

Answer: (c)C.

40

Why this answer is correct

The logic follows here, 

  • 10+12=11
  • 11+22=1511 + 2^2 = 15
  • 15+32=2415 + 3^2 = 24
  • 24+42=4024 + 4^2 = 40
  • 40+52=6540 + 5^2 = 65

Thus, the pattern is adding consecutive perfect squares (+1,+4,+9,+16,+25)(+1, +4, +9, +16, +25)

Hence, the correct answer is "Option 3"

Question 167

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)

    Sister

  2. BOption (b)

    Daughter

  3. COption (c)

    Mother's mother

  4. DOption (d)

    Sister's daughter

Correct answer

Answer: (d)D.

Sister's daughter

Why this answer is correct

Family Chart:

Let us first decode the given symbols and then draw a family tree.

Symbol×≠÷₹
MeaningFatherSonDaughterSister

Given: C ₹ D ≠ E ÷ L × M

  1. C ₹ D - 'C ₹ D' means C is the sister of D.

  2. D ≠ E - 'D ≠ E' means D is the son of E.

  3. E ÷ L - 'E ÷ L' means E is the daughter of L.

  4. L × M - 'L × M' means L is the father of M.

E and M are siblings (children of L). C and D are children of E. Therefore, C is the Sister's daughter of M.

Hence, the correct answer is "Option 4".

Select the set in which the numbers are related in the same way as are the numbers of the following sets.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

View answer & explanation

Correct answer

Answer: (d)D.

(6, 216, 18)

Why this answer is correct

The logic followed here is:

Logic: Second Number = (First Number × Third Number) × 2

For  (5, 120, 12)

⇒ (5 × 12) × 2

⇒ 60 × 2 = 120.

For  (3, 84, 14)

⇒ (3 × 14) × 2

⇒ 42 × 2 = 84.

Applying the same logic ,

(6, 216, 18)

⇒ (6 × 18) × 2

⇒ 108 × 2 = 216.

Hence, the correct answer is 'Option 4'.

Correct answer

Answer: (c)C.

Two

Why this answer is correct

Given number: 2563174

According to the conditions, if 2 is added to each odd digit and 1 is subtracted from each even digit in the number 2563174,

So, there are two digits (3 and 5) that appear more than once in the new number.

Hence, the correct answer is  'Option 3'.
