A school has 240 students. If 60% are girls, how many boys are there?

• A. 72
• B. 96
• C. 120
• D. 144

Answer: (B)

To find out how many boys are in the school, we'll begin by calculating the number of girls. Given that 60% of the 240 students are girls, we can find the number of girls by multiplying the total number of students by 60%.

The calculation is as follows:

Number of girls = 240 × 0.60 = 144.

Now that we know there are 144 girls, we can determine the number of boys by subtracting the number of girls from the total number of students:

Number of boys = Total students - Number of girls = 240 - 144 = 96.

Thus, there are 96 boys in the school. This matches the selection provided, demonstrating that the calculations are correct, and aligning with the question's requirement to determine the number of boys among the 240 students.
