Select the option in which the numbers shares the same relationship in set as that shared by the numbers in the given set.(Note : Operators should be performed on the whole numbers, without breaking down the numbers into its constituents digits. E.g. 13 - Operators 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)

(18, 9, 36)

(36, 18, 72)

(32, 16, 64)

(18, 9, 36)

(36, 18, 72)

The logic followed here is :

Second number × 2 = ist number and  Second number×4 =  IIIrd number

As

9 × 2 = 18 and 9 × 4 = 36

18 × 2 = 36 and 18 × 4 = 72

Similarly in option 1

16 × 2 = 32 and 16 × 4 = 64
