Answer 1

Given :

• Total number of students = 45
• Percentage of girls = 46%

To find :

Number of boys

Solution :

◈ Total Number of students = Number of girls + number of boys

◈ Total percentage = 100%

➠Percentage of students which are boys = Total percentage - Percentage of students who are girls

➠ Percentage of students who are boys = 100 - 46%

➠ Percentage of students who are boys = 54%

◈ Number of boys = 54% of total students

➠ Number of boys = (54/100) × 45

➠ Number of boys = 24.3

As Number of boys, can't be in decimal, so rounding off

➠ Number of boys = 24

Number of boys = 24
