Answer 3

Problem Analysis

We are given that the students in one group paid 600 tenge for tickets, while the students in the second group paid 480 tenge. The number of students in the first group is 4 more than the number of students in the second group. We need to determine the number of students in each group who visited the museum.

Solution

Let's assume that the number of students in the second group is x. Since the number of students in the first group is 4 more than the number of students in the second group, the number of students in the first group is x + 4.

We know that the students in the first group paid 600 tenge for tickets, and the students in the second group paid 480 tenge. Since the price per ticket is the same for both groups, we can set up the following equation:

600 * (x + 4) = 480 * x

Now, let's solve this equation to find the value of x.

600x + 2400 = 480x

600x - 480x = 2400

120x = 2400

x = 2400 / 120

x = 20

Therefore, there were 20 students in the second group. Since the number of students in the first group is 4 more than the number of students in the second group, there were 20 + 4 = 24 students in the first group.

So, 24 students visited the museum from the first group, and 20 students visited the museum from the second group.

Answer

There were 24 students in the first group and 20 students in the second group who visited the museum.
