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 /deleting /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, 5, 81)
(2, 5, 49)
Answer & explanation
Correct answer: option 3
(4, 5, 81)
(2, 5, 49)
The logic followed here is :
(Ist number + second number)2 = IIIrd number
As
(4 + 5)2 = 81
(2 + 5)2 = 49
same as (3, 5, 64)
(3 + 5)2 = 64
