Question

in a school, 1/10 of the students learnt french as optional language.of these 1/3 were girls. if 80 boys studied french, what is the total number of students in the school?

Answer 1

Answer:

1200 students

Step-by-step explanation:

Let the total no. of students in class= x

no of students study french= 1/10 of x= x/10

no. of girls studying french= 1/3 of x/10= x/30

no. of boys studying french=x/10 - x/30 = 2x/30 = x/15

but, no. of boys studying french= 80

so, x/15=80 => x= 15 X 80 = 1200

therefore, the total no. of students in school = 1200 students
