Correct Answer - Option 1 : C
Given:
Total students in the class is 42
Total number girls in the class is 18
Formula used:
Percentage= (Given value/Total value) × 100
Calculations:
According to the question, we have
The number of boys is
Number of boys = Total number of students - Total number of girls
⇒ Number of boys = 42 - 18
⇒ Number of boys = 24
The percentage of boys in the class is
Percentage of boys = (Number of boys/Total number of students) × 100
⇒ Percentage of boys = (24/42) × 100
⇒ Percentage of boys = 57.14% = 57%
∴ The percentage of boys out of total students in the class is 57%.
