Select the set in which the numbers are related in the same way as the numbers of the following set.
(9, 83, 164)
(4, 18, 34)
(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: D
Explanation
The correct answer is option 4 i.e. (6, 38, 74).
(9, 83, 164) → (92 + 2) = 83, (83 × 2) - 2 = 164
(4, 18, 34) → (42 + 2) = 18, (18 × 2) - 2 = 34
Similarly, (6, 38, 74) → (62 + 2) = 38, (38 × 2) - 2 = 74
