Answer:

60 percent

Explanation

Because 40 percent of girls will be there. The remaining 60 percent is boys,40 percent won’t come so 60 minus 40 is 20 percent and 40 plus 20 is 60 percent

Question:

In a class 40% of the students are girls and the rest are boys. If all the girls attended school but 40% of the boys stayed away what percent of the class was present in class.

Step by step explaination:

(There are two methods to do this sum)

First method:-

Since we have already been told that there are 40% girls, that means there are 60% boys (100–40).

The answer therefore will be 60% of 40, which is (60/100) × 40 = 24 boys.

Second method:-

The only difference is that we find out how many girls. Once we have the numbers of girls, we can then subtract the girls from the total number of students to get the number of boys.

Numbet of girls = (40/100)×40 = 16 girls

40–16 = 24 boys
