Answer 2

Problem Analysis

We are given that there were 29 students participating in the Olympiad. There was one difficult problem, one easy problem, and the rest were of medium difficulty. We also know that if a student solved the difficult problem, they also solved the easy problem. It is mentioned that 20 students did not solve the difficult problem, and 6 students did not solve the easy problem. We need to determine which problem was solved by more students and by how many more.

Solution

Let's analyze the given information step by step to find the solution.

1. Total number of students participating: 29. 2. Number of students who did not solve the difficult problem: 20. 3. Number of students who did not solve the easy problem: 6.

To find the number of students who solved the difficult problem, we subtract the number of students who did not solve it from the total number of students:

29 - 20 = 9

To find the number of students who solved the easy problem, we subtract the number of students who did not solve it from the total number of students:

29 - 6 = 23

Comparing the number of students who solved the difficult problem (9) and the number of students who solved the easy problem (23), we can see that more students solved the easy problem. The difference in the number of students who solved the easy problem compared to the difficult problem is:

23 - 9 = 14

Therefore, the easy problem was solved by more students, and the difference is 14.

Conclusion

Based on the given information, it can be concluded that the easy problem was solved by more students than the difficult problem, and the difference in the number of students who solved the easy problem compared to the difficult problem is 14.
