Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(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)
(144, 9, 3)
(225, 7, 8)
Answer & explanation
Correct answer: option 2
(144, 9, 3)
(225, 7, 8)
The logic followed here is :
(second number + IIIrd number)2 = Ist number
as
(9 + 3)2 = 144
(12)2 =144
(7 + 8)2 = 225
(15)2 = 225
same as (64, 5, 3)
(5 + 3)2 = 64
(8)2 = 64
