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)
(40, 120, 400) (18, 20, 78)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (29, 23, 98).
(40, 120, 400) = (40 × 1) + (120 × 3) = 40 + 360 = 400
(18, 20, 78) = (18 × 1) + (20 × 3) = 18 + 60 = 78
Similarly, (29, 23, 98) = (29 × 1) + (23 × 3) = 29 + 69 = 98
