Select the set in which the numbers are related in the same way as 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 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)
(13, 104, 16) (9, 63, 14)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (8, 60, 15)
The logic used here is:
(13, 104, 16) = 104 ÷ 13 = 8, 8 × 2 = 16
(9, 63, 14) = 63 ÷ 9 = 7, 7 × 2 = 14
Similarly;
(8, 60, 15) = 60 ÷ 8 = 15/2, (15/2) × 2 = 15
