Select the triad in which the numbers are related to each other in the same way as the numbers in 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.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 12-25-51.
Logic: 1st number × 2 + 1 = 2nd number; 2nd number × 2 + 1 = 3rd number
8-17-35 → 8 × 2 + 1 = 17; 17 × 2 + 1 = 35
23-47-95 → 23 × 2 + 1 = 47; 47 × 2 + 1 = 95
Similarly, 12-25-51 → 12 × 2 + 1 = 25; 25 × 2 + 1 = 51
