The Strength Of A School Is 2000. If 40% Of The Students Are Girls, Then How Many Boys Are There In The School?
Introduction
In this article, we will explore the concept of calculating the number of boys in a school given the total strength of the school and the percentage of girls. We will use a simple mathematical approach to solve this problem and provide a step-by-step guide to help readers understand the concept.
Understanding the Problem
The problem states that the total strength of a school is 2000 students. It is also given that 40% of the students are girls. We need to find out how many boys are there in the school.
Calculating the Number of Girls
To find the number of boys, we first need to calculate the number of girls in the school. We know that 40% of the students are girls, so we can calculate the number of girls as follows:
- Total strength of the school = 2000 students
- Percentage of girls = 40%
- Number of girls = (40/100) × 2000 = 800 students
Calculating the Number of Boys
Now that we have the number of girls, we can calculate the number of boys by subtracting the number of girls from the total strength of the school:
- Total strength of the school = 2000 students
- Number of girls = 800 students
- Number of boys = Total strength - Number of girls = 2000 - 800 = 1200 students
Conclusion
In this article, we calculated the number of boys in a school given the total strength of the school and the percentage of girls. We used a simple mathematical approach to solve this problem and provided a step-by-step guide to help readers understand the concept.

Q&A
Q: What is the total strength of the school?
A: The total strength of the school is 2000 students.
Q: What percentage of the students are girls?
A: 40% of the students are girls.
Q: How many boys are there in the school?
A: There are 1200 boys in the school.
Q: What is the formula to calculate the number of boys?
A: The formula to calculate the number of boys is:
Number of boys = Total strength - (Percentage of girls / 100) × Total strength
Q: How do I calculate the number of girls?
A: To calculate the number of girls, you can use the following formula:
Number of girls = (Percentage of girls / 100) × Total strength
Q: What if the percentage of girls is not given?
A: If the percentage of girls is not given, you can use the following formula to calculate the number of boys:
Number of boys = Total strength - Number of girls
Q: Can I use this formula to calculate the number of boys in a different school?
A: Yes, you can use this formula to calculate the number of boys in a different school as long as you have the total strength of the school and the percentage of girls.
Q: What if the total strength of the school is not given?
A: If the total strength of the school is not given, you will not be able to calculate the number of boys using this formula.
Q: Can I use this formula to calculate the number of girls?
A: Yes, you can use this formula to calculate the number of girls by rearranging the formula:
Number of girls = (Percentage of girls / 100) × Total strength
Q: What if the percentage of girls is not a whole number?
A: If the percentage of girls is not a whole number, you can still use this formula to calculate the number of boys. For example, if the percentage of girls is 40.5%, you can calculate the number of boys as follows:
Number of boys = Total strength - (40.5 / 100) × Total strength
Q: Can I use this formula to calculate the number of boys in a school with a different number of students?
A: Yes, you can use this formula to calculate the number of boys in a school with a different number of students as long as you have the total strength of the school and the percentage of girls.
