Select the set in which the numbers are related in the same way as are the numbers of the following set.
(34, 17, 27)
(42, 21, 31)
(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.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (54, 27, 37).
(34, 17, 27) → (17 + 27) - 10 = 44 - 10 = 34
(42, 21, 31) → (21 + 31) - 10 = 52 - 10 = 42
Similarly, (54, 27, 37) → (27 + 37) - 10 = 64 - 10 = 54
