Select the set in which the numbers are related in the same way as the numbers of the following set.(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.)
(20, 30, 450)
(35, 25, 540)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (7, 18, 225)
The logic used here is:
(20, 30, 450) = 20 + 30 = 50, 50 × 9 = 450
(35, 25, 540) = 35 + 25 = 60, 60 × 9 = 540
Similarly,
(7, 18, 225) = 7 + 18 = 25, 25 × 9 = 225
