Given:
Ratio of students in two classes = 5:7
10 students left from each class

To find:
Number of students in each class

Solution:
Let the initial number of students in the two classes be 5x and 7x respectively.

After 10 students leave from each class, the number of students in the two classes becomes (5x - 10) and (7x - 10) respectively.

According to the given condition, (5x - 10)/(7x - 10) = 4/6
Solving the above equation, we get:
30x - 60 = 28x - 40
2x = 20
x = 10

Therefore, the initial number of students in the two classes are:
5x = 5 × 10 = 50
7x = 7 × 10 = 70

Hence, the number of students in each class is 50 and 70 respectively.

Therefore, option D is the correct answer.
