Question

In a class the number of boys is 3 /2 times the number of girls. If there are 55 students in the class, find the number of boys and girls.

Answer 1

Answer:

There are 22 girls and 33 boys.

Step-by-step explanation:

Let b be the number of boys and g the number of girls.

We are told that:

b = (3/2) g

b + g = 55

Substituting the first equation into the second:

(3/2) g  + g = 55

=> (5/2) g = 55

=> g = 55 × 2 / 5 = 11 × 2 = 22

and b = 55 - g = 55 - 22 = 33.
