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

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

(1, 6, 4)

(3, 15, 9)

Answer 1

LOGIC: Second Number - (First Number \(×\) 2) = Third Number

Given:

(1, 6, 4) ⇒ 6 - (1 × 2) = 4

and

(3, 15, 9) ⇒ 15 - (3 × 2) = 9

Similarly, applying the same logic to the given options, we get

1) (9, 25, 7) ⇒ 25 - (9 × 2) = 7 (Follows).

2) (3, 18, 8) ⇒ 18 - (3 × 2) = 12 ≠ 8 (Does not follow).

3) (2, 16, 8) ⇒ 16 - (2 × 2) = 4 ≠ 8 (Does not follow).

4) (10, 33, 11) ⇒ 33 - (10 × 2) = 13 ≠ 11 (Does not follow).

Thus, the set (9, 25, 7) follows the same logic.

Hence, the correct answer is '(9, 25, 7)'.
