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)
(30, 93, 1) (42, 132, 2)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (3, 30, 7).
(30, 93, 1) = 30 + 1 = 31, 31 × 3 = 93
(42, 132, 2) = 42 + 2 = 44, 44 × 3 = 132
Similarly,
(3, 30, 7) = 3 + 7 = 10, 10 × 3 = 30
