Select the option in which the numbers share the same relationship in set as that shared by the numbers in the given 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)
(39, 78, 81)
(42, 84, 87)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3, i.e., (84, 168, 171).
(39, 78, 81) → 39 2 = 78, 78 + 3 = 81
(42, 84, 87) → 42 2 = 84, 84 + 3 = 87
Similarly, (84, 168, 171) → 84 2 = 168, 168 + 3 = 171
