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.)
(15, 20, 4) (30, 30, 3)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (60, 400, 20)
The logic used here is:
(15, 20, 4) = (20 ÷ 4) × 3 = 5 × 3 = 15
(30, 30, 3) = (30 ÷ 3) × 3 = 10 × 3 = 30
Similarly,
(60, 400, 20) = (400 ÷ 20) × 3 = 20 × 3 = 60
