Question

A gardener has 1000 plants. He wants to plant these in such a way that the number of rows and the number of columns remain same. Find the minimum number of plants, he needs more for this?

Answer 1

If there are equal number of rows and columns, the number of plants should be a perfect square. The closest perfect square to 1000 and greater than it is 1024. Thus, he requires 24 more plants to complete the arrangement.
