Answer 1

Given :

• Total Number of students in the school = 2000
• Percentage of girIs = 30%

To Find :

• The total number of boys in the school.

Solution :

In the question, it is given that total number of students in the school is 2000 and percentage of girIs is 30% and we have to find the total number of boys. So for that, we will find the total number of the girIs after that we will substract the total number of girIs from total number of students to get the total number of boys in the school.

Let's Assume,

• The total number of boys be x

Finding the Total number of girls :

• Total number of girIs = 30% of Total number of Students
• Total number of girIs = 30/100 × 2000
• Total number of girIs = 30 × 20
• Total number of girls = 600

Finding the Total number of boys :

• Total number of boys + Total number of girIs = Total number of students
• x + 600 = 2000
• x = 2000 - 600
• x = 1400

Therefore :

• The total number of boys in the school is 1400.
