(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)
(14, 28 , 84)
(17, 34, 102)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (21, 42, 126).
Logic: (14, 28 , 84)
14 × 2 = 28 × 3 = 84
(17, 34, 102)
17 × 2 = 34 × 3 = 102
Similarly, (21, 42,126)
21 × 2 = 42 × 3 = 126.
