Question

I
n a school number of girls is 60 more than number of boys total number of students in school is 450. set up an equation to find the number of boys in the school?​

Answer 1

Answer:

480 boys .

Step-by-step explanation:

Percentage of boy students = 60%

Number of girl students = 320

Number of boy students

We are given that boys are 60% then girls will be 40% so by using percentage formula we will find out the total number of students.

Total students. = 320 × 100 / 40

Total number of students = 800 .

Now we have the total number of students so we will find the number of boys .

Number of boys = 60 × 800 /100

Number of boys = 480 boys .

Answer 2

Answer:

Let the number of boys = x

So number of girls = X + 60

Total = 450

Equation = x + x + 60 = 450

2x + 60 = 450

2x = 450 - 60 = 390

x = 390 / 2 = 195

Boys = 195

Girls = 195 + 60 = 255

Verification :- Total students = 450 ( given )

195 + 255 =450
