Answer 1

Answer: - The total students in the school is 900.

Step-by-step explanation:

Ratio of Girls and boys in school = 5:7

Boys in the school = 150

Total students in the school = ?

Let take the number 5x and 7x respectively

Difference of the ratios ,

7x - 5x = 2x

So,

2x = 150

x = 150 / 2

x = 75

We have to find the total number of students in school so,

Sum of the ratios,

7 + 5 = 12

75 × 12 = 900

The total students in the school is 900.

Answer 2

Answer:

Heyy there , here is the solution

Step-by-step explanation:

the ratio of number of girls to the number of boys = 5:7

Let the number of girls be 5x

Then the number of boys is 7x

Given there are 150 MORE boys than girls

so, number of boys- number of girls= 150

7x-5x=150

2x=150

x=75

Number of girls= 5x=375

Number of boys=7x=525

Total students= 375+525= 900
