Answer 1

Answer:

Step-by-step explanation:

Let be the total no. of students be x

If boys =5/8  

Then A/Q

5x/8+240=x

5x/8-x=-240

-3x/8=-240

3x/8=240

3x=240×8

x=240×8/3

x=640

Boys =640-240

         =400boys

Answer 2

let the total no. of the student be x

Boys r 5/8 of total student

so, the number of boys will be (5/8) × x

Then

$\frac{5x}{8} + 240 = x$

$\frac{5x + 1920}{8} = x$

5x + 1920 = 8x

1920 = 8x - 5x

1920 = 3x

$\frac{1920}{3} = x$

640 = x

The total number of students is 640

the number of boys =

$\frac{640 \times 5}{8} = 400$

The number of boys are 400
