    Solution :

    From this we come to know that the square root of the given number (4000) is greater than 632

    632  =  3969

    4000 - 3969  =  31

    In order to convert the given number as the square of 63, we have to subtract 31.

    Hence 31 is the least number to be subtracted from 4000 to get a perfect square.
