Answer 2

Given:

The boys and girls in the ratio of 3:4. The number of girls is 240.

To find:

The number of boys.

Solution:

The number of boys is 180.

To find the answer, we will follow the following steps:

As given, we have,

The ratio of boys to girls = 3:4

Let the common ratio between the number of boys and girls be x.

So,

The number of boys = 3x

and

The number of girls = 4x

Also,

The number of girls = 240

So,

$4x = 240$

$x = 60$

Now,

On putting the value of x in 3x,

The number of boys

$= 3(60)$

$= 180$

Hence, the number of boys is 180.
