Answer 3

Problem Analysis

We are given that 211 papers were submitted for a competition. Some of these papers were distributed equally among 3 sections. We need to determine how many papers are left, either 64 or 66.

Solution

To find the number of papers left, we need to subtract the number of papers distributed among the sections from the total number of papers.

Let's calculate the number of papers distributed among the sections. Since the problem does not provide the exact number of papers distributed, we will consider both possibilities: 64 and 66.

Case 1: Assuming 64 papers were distributed If 64 papers were distributed among 3 sections, each section would receive 64/3 = 21.33 papers. Since we cannot have a fraction of a paper, we need to round down to the nearest whole number. Therefore, each section would receive 21 papers.

To find the number of papers left, we subtract the number of papers distributed from the total number of papers: 211 - (21 * 3) = 211 - 63 = 148 papers left.

Case 2: Assuming 66 papers were distributed If 66 papers were distributed among 3 sections, each section would receive 66/3 = 22 papers.

To find the number of papers left, we subtract the number of papers distributed from the total number of papers: 211 - (22 * 3) = 211 - 66 = 145 papers left.

Therefore, the correct answer is that there are 145 papers left, not 64 or 66.

Conclusion

Based on the given information, there are 145 papers left after distributing some of them equally among 3 sections.
