Question

40%of student in a school are girls if total girls are 150 find total boys​

Answer 1

Step-by-step explanation:

let the total number of boys and girls "x"

x = 40/100 = 150

x = 150*100 = 375

375 - 150 = 225

therefore total boys are 225

Answer 2

Answer:

225 boys.

Step-by-step explanation:

Let the number of students in the school be x.

∴ 40% of x = 150

⇒ 40/100 × x = 150              ($\frac{40}{100} = \frac{40/20}{10/20} = \frac{2}{5}$)

⇒ 2x/5 = 150

⇒ x = $\frac{150*5}{2}$ = 375

Number of boys = (total number of students - total number of girls)

= 375 - 150 = 225
