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)
Answer & explanation
Correct answer: option 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
