Question

There are 500 flowers with a gardener he has to arrange theming such a way that flowers in the rows is same as the flowers in coloum
i) how much flowers will he have to remove
ii) how much would he require more

Answer 1

Suppose we have B rows and B flowers in it. because Number of rows and flowers in it are same.

so total number of flowers will be = B*B

= B^2

So we have find number whose square is near 500.

i.e = 22

so 22*22 = 484

we have to remove 16 Flowers.

for addition of flowers we must find number whose square is greater than 500.

i.e 23

so 23*23 = 529.

so we have to add 29 flowers.
