One incorrect solution to this problem is to say that Alice is 10 years old, Bob is 10 years old, and Carol is 10 years old. This solution is incorrect because the sum of their ages would be 30, not 30.

The correct solution to the problem is to say that Alice is 12 years old, Bob is 9 years old, and Carol is 9 years old. This solution is correct because the sum of their ages is 30.

Why the Incorrect Solution is Incorrect

The incorrect solution is incorrect because it violates the problem's constraints. The problem states that the sum of the kids' ages is 30. However, the incorrect solution results in a sum of ages that is less than 30.

Specifically, the incorrect solution results in a sum of ages of 20. This is because Alice, Bob, and Carol are all 10 years old in the incorrect solution.

The Correct Solution

The correct solution to the problem is to say that Alice is 12 years old, Bob is 9 years old, and Carol is 9 years old. This solution is correct because it satisfies the problem's constraints.

Specifically, the correct solution results in a sum of ages of 30. This is because Alice is 12 years old, Bob is 9 years old, and Carol is 9 years old.

In this article, we have taken a closer look at an incorrect solution to The Math Kids problem and explained why it is incorrect. We have also provided a correct solution to the problem.

It is important to remember that when solving math problems, it is important to carefully consider the problem's constraints. If you do not consider the problem's constraints, you may end up with an incorrect solution.
