Answer 2

Given:

Total students=2,000

Girls=40%

To find:

The number of boys

Solution:

The required number of boys is 1200.

We can obtain the number of boys by calculating the remaining per cent of the total students present in the class.

The % of girls=40%

So, the remaining %=100%-40%

=60%

The per cent of boys=60%

Now, the required number of boys=60% of 2,000

=60/100×2000

=6×200

=1200

So, there are 1200 boys.

Therefore, the required number of boys is 1200.
