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)
(4, 5, 20)
(7, 8, 56)
Answer & explanation
Correct answer: option 3
(4, 5, 20)
(7, 8, 56)
The logic followed here is :
(second number × Ist number) = IIIrd number
as
(5 × 4) = 20
(8 × 7) = 56
Therefore (7, 12, 84)
(12 × 7) = 84
