Question

Q7. In a class of 35 students
the numbers of girls is 2 / 5
times the number of boys. Find the number of boys in the class ?​

Answer 1

Answer:

10 girls

Step-by-step explanation:

no. of students= 35

let the no. of boys be = y

no. of girls = 2/5 of y

y + 2/5 of y = 35

7y /5 = 35

7y= 175

y= 175/7

y= 25

no. of boys = 25

no. of girls = 2/5 of boys

=2/5 × x

=10 girls
