Select the triad in which the numbers are related in the same way as are the numbers of the following triads.
(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/deleting/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.)
(2, 3, 17)
(5, 2, 21)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (3, 4, 23)
Logic: First number × Second number + 11 = Third number
(2, 3, 17): (2 × 3) + 11 = 6 + 11 = 17
(5, 2, 21): (5 × 2) + 11 = 10 + 11 = 21
Similarly, (3, 4, 23): (3 × 4) + 11 = 12 + 11= 23
