84 is related to 21 following a certain logic. Following the same logic, 180 is related to 45. To which of the following is 252 related following the same logic? (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/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.)

Given: 84 is related to 21 , 180 is related to 45, 252 is related to ?

​Logic: Each number is divided by 4 to get the related number.

84 ÷ 4 = 21 

180 ÷ 4 = 45 

Similarly;

252: ? 

Thus, the correct answer is (A) 63.
