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 their 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
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 6-9-74.
12-15-200 → (12 × 15) + 20 = 200
10-12-140 → (10 × 12) + 20 = 140
Similarly, 6-9-74 → (6 × 9) + 20 = 74
