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. 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(18, 7, 119) (11, 9, 90)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (12, 4, 44).
The logic used here is:
(18, 7, 119)
18 × 7 - 7 = 126 - 7 = 119
(11, 9, 90)
11 × 9 - 9 = 99 - 9 = 90
Similarly,
(12, 4, 44)
12 × 4 - 44 = 48 - 4 = 44
