In a class of 49 students, the ratio of girls to boys is 4:3. If 4 girls leave the class, the ratio of girls to boys would be

- 11:7
- 8:7
- 6:5
- 9:8

**Answer**

Let the number of girls and boys be 4x and 3x.

4x + 3x = 49

7x = 49

x = 7

So, the number of girls and boys are 28 and 21 respectively.

After 4 girls leave the class, number of girls = 28 - 4 = 24

New ratio of girls to boys = 24:21

= 8:7

**The correct option is B.**
