Question

the ratio of girls and boys in a school is 5 is to 7 if there is 150 more boys in the school then find the total students in the school​

Answer 1

Step-by-step explanation:

Let the number of boys and girls be 5x and 7x respectively.

according to your question,

7x = 5x + 150

or 7x - 5x = 150

or 2x = 150

or x = 150/2

or x = 75

Therefore, total strength of class

= 5x + 7x = 12x = 12×45 = 540

Answer 2

Answer:

Step-by-step explanation:

Given

ratio 5:7

no. of boys more than girls = 150

as total no.of girls and boys = 5x+7x

given difference between boys and girls

= 150

7x-5x = 2x

150 = 2x

therefore x = 75

therefore no. of students = 5x + 7x

= 12x

= 12×75=900
