Solution
The correct option is B 159
First we have to find the square root of 16800 by long Division method.
This shows that (129)² is less than 16800 by 159, So the least number to be subtracted from 16800 is 159.
Required perfect Square number= 16800- 159= 16641
√16641 = 129
Hence , the required this number is 159.
