Q.8  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.

Answers (1)

It is given that the number of rows and the number of columns are the same.

Let a number of rows or number of columns be x.

The number of plants required  =  x^2

The gardener has 1000 plants.

We need to find a perfect square just greater than 1000.

We know,            31^2 = 961          and         32^2 = 1024

So the minimum plants needed by gardener = 1024 - 1000 = 24 plants.
