Verified Answer
A picnic is being planned in a school for Class VII. Girls are 60% of ...
Let total students be x
60/100* x = 18
x = 30
boys = 30−18 = 12
ratio of girls/ ratio of boys = 18 /12 = 3/2
60/100* x = 18
x = 30
boys = 30−18 = 12
ratio of girls/ ratio of boys = 18 /12 = 3/2
So option C is the correct answer.

A picnic is being planned in a school for Class VII. Girls are 60% of ...
Total Number of Students
To determine the total number of students in Class VII, we know that girls make up 60% of the total. Given that there are 18 girls, we can set up the equation:
- Let the total number of students be \( x \).
- Since girls constitute 60% of the total, we have:
\[
0.6x = 18
\]
- Solving for \( x \):
\[
x = \frac{18}{0.6} = 30
\]
Thus, the total number of students in Class VII is 30.
Number of Boys
Now, we can find the number of boys in the class:
- Total students = 30
- Number of girls = 18
Calculating boys:
- Number of boys = Total students - Number of girls
- Number of boys = 30 - 18 = 12
Ratio of Girls to Boys
Now, we need to determine the ratio of the number of girls to the number of boys:
- Number of girls = 18
- Number of boys = 12
The ratio can be expressed as:
\[
\text{Ratio} = \frac{\text{Number of girls}}{\text{Number of boys}} = \frac{18}{12}
\]
- Simplifying this ratio:
\[
\frac{18 \div 6}{12 \div 6} = \frac{3}{2}
\]
Conclusion
The ratio of the number of girls to the number of boys in Class VII is 3:2. Therefore, the correct answer is option 'C'.

Thus, the total number of students in Class VII is 30.
Number of Boys
Now, we can find the number of boys in the class:
- Total students = 30
- Number of girls = 18
Calculating boys:
- Number of boys = Total students - Number of girls
- Number of boys = 30 - 18 = 12
Ratio of Girls to Boys
Now, we need to determine the ratio of the number of girls to the number of boys:
- Number of girls = 18
- Number of boys = 12
The ratio can be expressed as:
\[
\text{Ratio} = \frac{\text{Number of girls}}{\text{Number of boys}} = \frac{18}{12}
\]
- Simplifying this ratio:
\[
\frac{18 \div 6}{12 \div 6} = \frac{3}{2}
\]
Conclusion
The ratio of the number of girls to the number of boys in Class VII is 3:2. Therefore, the correct answer is option 'C'.
