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.)

(9, 55, 64)

(7, 43, 50)

(5, 31, 36)

(9, 55, 64)

(7, 43, 50)

The logic followed here is :

Ist number + second number   =   Third number 

as

9 + 55 = 64

7 + 43 = 50

Therefore option 4

5 + 31 = 36
