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)
(11, 78, 15) (12, 90, 18)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (13, 96, 19)
The logic used here is:
(11, 78, 15) = 11 + 15 = 26, 26 × 3 = 78
(12, 90, 18) = 12 + 18 = 30, 30 × 3 = 90
Similarly,
(13, 96, 19) = 13 + 19 = 32, 32 × 3 = 96
Hence, the correct answer is (13, 96, 19) .
