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.)
12-15-200 and 10-12-140

Correct option is B

Logic: (I number × II number) + 20 = III number
12 - 15 - 200
(12 × 15) + 20 = 180 + 20 = 200
10 - 12 - 140
(10 × 12) + 20 = 120 + 20 = 140
6 - 9 - 74
(6 × 9) + 20 = 54 + 20 = 74
