Question

In a class of 35 students, the number of girls is two - fifth the number of boys. find the number of boys in class?

Answer 1

Answer:

Step-by-step explanation:

let us assume no of boys = x

no of girls  = 2/5 of boys

                  = 2/5*x

x+2x/5 = 35

LCM 5

(5x+2x)/5 =  35

7x = 35*5

7x = 175

x = 175/7

x= 25

no of boys in class  = 25

no of girls  = 2/5*25

                  =10
