Select the set in which the numbers are related in the same way as are the numbers of the given set.
(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its 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.)
(4, 81, 5)
(3, 144, 9)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (2, 100, 8).
Logic: (4, 81, 5)
4 + 5 = 9
(9)2 = 81
(3, 144, 9)
3 + 9 = 12
(12)2 = 144
Similarly, (2, 100, 8)
2 + 8 = 10
(10)2 = 100.
