Answer 2

Given,

The ratio of the number of male teachers of two female teachers in a school is found to be 3:2. There are 30 male teachers.

To find,

The number of female teachers.

Solution,

Let the number of male teachers = 3x

The number of female teachers = 2x.

The number of the male teacher is given to us i.e. 30 teachers.

⇒ 3x = 30

⇒ x = 30/3

⇒  x = 10

The number of female teachers is 2x ⇒ 2(10) = 20 teachers.

Therefore, the number of female teachers in the school is 20 teachers.
