Solution

The first step is to understand the initial ratio of students in schools A, B, and C, which is 5:6:8.

Next, we need to calculate the new number of students in each school after the increase.

For school A, the number of students is increased by 30%. So, the new ratio for A would be 5 * 1.30 = 6.5.

For school B, the number of students is increased by 25%. So, the new ratio for B would be 6 * 1.25 = 7.5.

For school C, the number of students is increased by 25%. So, the new ratio for C would be 8 * 1.25 = 10.

So, the new ratio of students in schools A, B, and C would be 6.5:7.5:10.

However, ratios should be expressed in whole numbers. To convert the ratio to whole numbers, we can multiply each term by 2, which gives us 13:15:20.

Therefore, the correct answer is 13:15:20.
