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 / subtracting / 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)
(30, 93, 1)
(42, 132, 2)
Answer & explanation
Correct answer: option 4
(30, 93, 1)
(42, 132, 2)
(Ist number + IIIrd number) × 3 = IIIrd number
Same as
(30 + 1) × 3 = 93
(42 + 2) × 3 = 132
Similarly In option 4
(3 +7 ) × 3 = 30
