Question: The ratio of the number of students in two classes is 5:6. If there are 60 students in the first class, how many students are in the second class?

Options:

1. 72
2. 66
3. 60
4. 54

Correct Answer: 72

Solution:

Let students in the first class be 5x and in the second class be 6x. Given 5x = 60, x = 12. Therefore, students in the second class = 6x = 6*12 = 72.
