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/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.)
(9, 36, 12) (12, 48, 16)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e (21, 84, 28)
Logic: 1st number × 4 = 2nd number, 2nd number ÷ 3 = 3rd number
(9, 36, 12) ⇒ 9 × 4 = 36, 36 ÷ 3 = 12
(12, 48, 16) ⇒ 12 × 4 = 48, 48 ÷ 3 =16
Similarly, (21, 84, 28) ⇒ 21 × 4 = 84, 84 ÷ 3 = 28
