Question

In a class of 49 students, number of girls is 2/5 of the boys. Find the number of boys
in the class.​

Answer 1

Answer:

Number of boys in the class = 35.  

Step-by-step explanation:

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!
