(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying 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. 87.
11 is related to 57 ⇒ 11 × 5 + 2 = 57
14 is related to 72 ⇒ 14 × 5 + 2 = 72
Similarly, 17 is related ⇒ 17 × 5 + 2 = 87
