A gardener has 10

Answer :

It is mentioned in the question that the gardener has 1000 plants.

And,


The number of rows and the number of columns is the same


We need to find the number of more plants that should be there, such that when the gardener plants them, the number of rows and columns are equal to one another.


For this, the number which should be added to 1000 to make it a perfect square has to be calculated


The square root of 1000 can be calculated by long division method as follows:



The remainder is 39. It represents that the square of 31 is less than 1000


The next number is 32 and 322 = 1024


Hence, number to be added to 1000 to make it a perfect square


= 322 - 1000


= 1024 - 1000


= 24


Thus, the required number of plants is 24.
