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 /deleting /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.)
(3, 5, 30)
(6, 5, 60)
Answer & explanation
Correct answer: option 2
(3, 5, 30)
(6, 5, 60)
The logic followed here is :
(Ist number × second number ) × 2 = IIIrd number
as
(3 × 5 ) × 2 = 30
(6 × 5) × 2 = 60
Therefore in (6, 7, 84)
(6 × 7) × 2 = 84
