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)
(55, 11, 25) (64, 16, 16)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (33, 11, 9)
The logic used here is:
(1st number ÷ 2nd number)2 = 3rd number
(55, 11, 25) = 55 ÷ 11 = 5, 52 = 25
(64, 16, 16) = 64 ÷ 16 = 4, 42 = 16
Similarly,
(33, 11, 9) = 33 ÷ 11 = 3, 32 = 9
