Question

A gardener has 1000 plants he wants to plant these is such a way that the number of rows and the number of colums remain same . find the minimum number of plants he needs more for these

Answer 1

If the number of rows and number of columns are to be equal, then the total number of trees will be in the form of x2, which is nothing but a perfect square.

As 1000 is not a perfect square, you need to check for a perfect square above and nearest to 1000. 

It's 1024, which is square of 32. So he needs to add 24 more trees to get 1024

Answer 2

There will be 32 rows and 32 columns and he needs 24 more plants for purpose
