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.)
(15, 21, 66) (9, 17, 44)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (5, 37, 52)
The logic used here is:
(15, 21, 66) = 66 - 21 = 45, 45 ÷ 3 = 15
(9, 17, 44) = 44 - 17 = 27, 27 ÷ 3 =9
Similarly,
(5, 37, 52) = 52 - 37 = 15, 15 ÷ 3 = 5
