Question

in a class of 35 students the number of girls is 2/5 of the boys. find the number of boys in the class.
​

Answer 1

Answer:

number of students in the class = 35

let the number of boys in the class be x

number of girls in the class = 2/5x

x+2/5x = 35

5x+2x/5 = 35

7x = 35*5

x = 175/7

x = 25 .

Number of boys = 25

Number of girls = 2/5*25 = 10 .
