Answer 1

no. of boys is 35 and nô. of girls is 14

Answer 2

Let the number of boys = x.

Then the number of girls will be 2/5 of the boys = 2/5 * x.

Given that Total number of students = 49.

x + 2/5 * x = 49

7/5 * x = 49

7x = 49 * 5

x = 245/7

x = 35.

Therefore the number of boys in the class = 35.


Hope this helps!
