Question:

Select the set in which the numbers are related in the same way as  are the numbers of the following 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).

(16, 7, 81)

(24, 16, 64)

 

Options:

(13, 7, 36)

(48, 39, 18)

( 37, 25, 100)

(21, 19, 8)

Correct Answer:

(13, 7, 36)

Explanation:

(16, 7, 81)

(24, 16, 64)

The logic followed here is :

( Ist number  -  second number )2 = Third number

( 16  -  7 )2 =  92 = 81

( 24  - 16 )2 = 82 = 64

similarly in option 1

(13, 7, 36)

( 13 - 7 )2 = 62 = 36
