Question

the ratio between male and female teacher is 5. 8 if there are 56 female teachers the number of male teacher in the school is

Answer 1

Given ratio between male and female teachers

= 5 : 8

Number of female teachers = 56
Let number of male teachers be x

By Using Ratio and proportion method

=> 5 : 8 :: x : 56

Product of extreme = Product of mean

=> 8x = 56 × 5

=> x = (56 × 5) / 8

=> x = 7 × 5

=> x =35

So there are 35 male teachers.

Answer 2

Using ratio and proportion

Let male teacher =x

5:8::x:56
Formula:- Product of mean=Product of extreme

8×x=5×56
8x=280
x=35

Male teacher=35
