Answer 2

Answer:

The number of boys enrolled in that class= 40 students

Step-by-step explanation:

In the above question:

Given:

Boys absent= 15%

Boys absent= 34

To find:

The number of boys enrolled in that class?

Solution:

Assuming the total strength as 100%

Absent= 15%

Present= 100%-15%

           = 85%  

Let,

The total number of students in school = k

so, 85%of k = 34

     85/100 of k = 34

      85k = 3400                  

           k = 3400/85

           k = 40

The number of boys enrolled in that class= 40
