Answer

To solve the problem step by step, we need to analyze the information given about the workers in M/s. Nottam Dibbawala Pvt. Ltd. and derive the number of unmarried women who are graduates.

### Step-by-Step Solution:

1. **Total Workers**: There are 60 workers in total.
- **Women Workers**: 25 are women.
- **Men Workers**: Therefore, the number of men = Total Workers - Women Workers = 60 - 25 = 35 men.

2. **Married Workers**: Out of the total workers, 28 are married.
- **Married Men**: 15 men are married.
- **Married Women**: Therefore, the number of married women = Total Married Workers - Married Men = 28 - 15 = 13 married women.

3. **Graduated Workers**: 26 workers are graduates.
- **Graduated Men**: 15 men are graduates.
- **Graduated Women**: Therefore, the number of graduated women = Total Graduated Workers - Graduated Men = 26 - 15 = 11 graduated women.

4. **Married Graduated Workers**: 20 married workers are graduates, of which 9 are men.
- **Married Graduated Women**: Therefore, the number of married graduated women = Total Married Graduated Workers - Married Graduated Men = 20 - 9 = 11 married graduated women.

5. **Analysis of Married Graduated Women**:
- We found that there are 11 married graduated women.
- We also found that there are 13 married women in total.

6. **Unmarried Graduated Women**:
- Since there are 11 married graduated women out of a total of 11 graduated women, this implies that all graduated women are married.
- Therefore, the number of unmarried graduated women = Total Graduated Women - Married Graduated Women = 11 - 11 = 0.

### Final Answer:
The number of unmarried women who are graduates is **0**.
