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 its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /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.)
(76, 152, 38) (84, 168, 42)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (68, 136, 34).
Logic:
(76, 152, 38) ⇒ 38 × 2 = 76; 76 × 2 = 152
(84, 168, 42) ⇒ 42 × 2 = 84; 84 × 2 = 168
Similarly, ( 68, 136, 34) ⇒ 34 × 2 = 68; 68 × 2 = 136.
