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)
Answer & explanation
Correct answer: option 2
(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
