Question

Answer

Problem:
A school has 560 students. If the number of boys is 7 times the number of girls, then the number of girls in the school is:

Solution:
Let's assume the number of girls in the school is 'x'.

Given that the number of boys is 7 times the number of girls, we can say that the number of boys is 7x.

We know that the total number of students in the school is 560. So, we can write the equation:

x + 7x = 560

Simplifying the equation:

8x = 560

Dividing both sides of the equation by 8:

x = 560/8

x = 70

Conclusion:
The number of girls in the school is 70. Therefore, option 'C' is the correct answer.
