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, 4, 24)
(4, 5, 40)
Answer & explanation
Correct answer: option 4
(3, 4, 24)
(4, 5, 40)
The logic followed here is :
( Ist number × second number)×2 = IIIrd number
as
( 3 × 4) × 2 = 24
( 4 × 5) × 2 = 40
same as in (2, 7, 28)
(2 × 7) × 2 = 28
