**Given:**
- The picnic is being planned for Class VII.
- Girls constitute 60% of the total number of students.
- There are 18 girls in the class.
**To find:**
The ratio of the number of girls to the number of boys in the class.
**Solution:**
Let's assume the total number of students in the class is 'x'.
- Girls constitute 60% of the total number of students, which means they are 60/100 * x = 3x/5 in number.
- We are given that the number of girls is 18. So, we have the equation 3x/5 = 18.
To find the value of 'x', we can solve this equation.
3x/5 = 18
3x = 18 * 5
3x = 90
x = 90/3
x = 30
Therefore, the total number of students in the class is 30.
Now, we can find the number of boys in the class.
Number of boys = Total number of students - Number of girls
Number of boys = 30 - 18 = 12
The ratio of the number of girls to the number of boys in the class is 18:12, which simplifies to 3:2.
Hence, the correct answer is option 'B' - It is 3:2.
- The picnic is being planned for Class VII.
- Girls constitute 60% of the total number of students.
- There are 18 girls in the class.
**To find:**
The ratio of the number of girls to the number of boys in the class.
**Solution:**
Let's assume the total number of students in the class is 'x'.
- Girls constitute 60% of the total number of students, which means they are 60/100 * x = 3x/5 in number.
- We are given that the number of girls is 18. So, we have the equation 3x/5 = 18.
To find the value of 'x', we can solve this equation.
3x/5 = 18
3x = 18 * 5
3x = 90
x = 90/3
x = 30
Therefore, the total number of students in the class is 30.
Now, we can find the number of boys in the class.
Number of boys = Total number of students - Number of girls
Number of boys = 30 - 18 = 12
The ratio of the number of girls to the number of boys in the class is 18:12, which simplifies to 3:2.
Hence, the correct answer is option 'B' - It is 3:2.
