Select the triad in which the numbers are related in the same way as are the numbers of the following triads.
4 - 5 - 14
7 - 8 - 20
(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: C
Explanation
The correct answer is option 3 i.e. 9 - 12 - 26.
4 - 5 - 14 → (4 + 5) + 5 = 14
7 - 8 - 20 → (7 + 8) + 5 = 20
Similarly, 9 - 12 - 26 → (9 + 12) + 5 = 26
