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)

(12, 42, 7)

(13, 52, 8)

(9, 18, 4)

(12, 42, 7)

(13, 52, 8)

The logic followed here is :

First number × (IIIrd number ÷ 2 ) = Second number

As

12 × ( 7 ÷ 2 ) = 42

13 × ( 8 ÷ 2 ) = 52

Same as in option 4

 9 × ( 4 ÷ 2 ) = 18
