10 is related to 15 following a certain logic. Following the same logic, 42 is related to 63. To which of the following numbers is 22 related, following the same logic?
(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: C
Explanation
The correct answer is option 3 i.e. 33.
Logic: Second number = First number + 1/2 of First number
10 is related to 15 = 10 + (10 × 1/2) = 10 + 5 = 15
42 is related to 63 = 42 + (42 × 1/2) = 42 + 21 = 63
Similarly, 22 is related to 33 = 22 + (22 × 1/2) = 22 + 11 = 33
