Sports School Enrollment and Group Sizes

The sports school is currently accepting children for sports training in three disciplines: running, jumping, and ball throwing. The number of children enrolled in each group is as follows:

- Running: 15 children - Jumping: 17 children - Ball throwing: 13 children

Tanya, one of the children in the sports school, observed the group sizes and made a statement. She said that if 2 children from the jumping group were to transfer to the ball throwing group, then all the groups would have an equal number of children. The question is whether Tanya's statement is correct.

Analyzing Tanya's Statement

To determine if Tanya's statement is correct, we need to consider the current group sizes and the potential transfer of 2 children from the jumping group to the ball throwing group.

Currently, the group sizes are as follows:

- Running: 15 children - Jumping: 17 children - Ball throwing: 13 children

If 2 children from the jumping group were to transfer to the ball throwing group, the new group sizes would be:

- Running: 15 children - Jumping: 15 children (17 - 2) - Ball throwing: 15 children (13 + 2)

Now, let's compare the group sizes:

- Running: 15 children - Jumping: 15 children - Ball throwing: 15 children

As we can see, after the transfer, all the groups would indeed have an equal number of children, with each group having 15 children. Therefore, Tanya's statement is correct.

Conclusion

Tanya is correct in stating that if 2 children from the jumping group transfer to the ball throwing group, then all the groups in the sports school will have an equal number of children.
