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 /deleting /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)
(45, 9, 12) (21, 3, 14)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (80, 10, 15)
The logic used here is:
(45, 9, 12) = 45 ÷ 9 = 5, 5 + 7 = 12
(21, 3, 14) = 21 ÷ 3 = 7, 7 + 7 = 14
Similarly,
(80, 10, 15) = 80 ÷ 10 = 8, 8 + 7 = 15
