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)
(20, 6, 4) (24, 7, 5)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1. i.e. (65, 9, 4).
(20, 6, 4) = 62 - 42 = 36 - 16 = 20
(24, 7, 5) = 72 - 52 = 49 - 25 = 24
Similarly, (65, 9, 4) = 92 - 42 = 81 - 16 = 65
