    Correct Answer: 16


    Solution : Check whether 63520 is a perfect square using the division method:

    Remainder = 16
    Hence, 63520 is not a perfect square.
    ⇒ 63520 – 16 = 63504 is a perfect square.
    So, the least number that should be subtracted is 16.
    Hence, the correct answer is 16.
