Question:

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)

(8, 540, 60)
(9, 70, 7)

Options:

(12, 56, 60)

(8, 63, 7)

(9, 54, 12)

(9, 45, 7)

Correct Answer:

(8, 63, 7)

Explanation:

(8, 540, 60)

(9, 70, 7)

Logic followed here is :

(Ist number × Third number)  + third number = second number

(8 × 60)  + 60  = 540

same as

(9 × 7)  + 7  = 70

Similarly in option 2

(8 × 7)  + 7  = 63
