Answer 2

Answer:

The percentage of girls in the class is 60%.

The number of boys is 16.

Step-by-step explanation:

Let the percentage of students in the class is 100%.

40% of the total students are boys.

Therefore, percentage of girls in the class = (100-40)% = 60%.

Now, let the total number of students in the class be x.

Number of girls = 24 = 60% of x.

.·. x = 24/60% = (24*100)/60 = 2400/60 = 40.

So, there are 40 students in the class out of which 24 are girls.

.·. Number of boys in the class = 40-24 = 16.
