Answer

To solve the problem of how many papers an average typist types per minute, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understand the Given Information**:
- Total typists = 123
- Total papers typed = 984
- Total time taken = 1/15 hour

2. **Convert Time from Hours to Minutes**:
- Since 1 hour = 60 minutes, we can convert 1/15 hour into minutes:
\[ \text{Time in minutes} = \frac{1}{15} \times 60 = 4 \text{ minutes} \]

3. **Calculate the Total Papers Typed per Minute**:
- To find the total number of papers typed per minute, we divide the total number of papers by the total time in minutes:
\[ \text{Total papers per minute} = \frac{984 \text{ papers}}{4 \text{ minutes}} = 246 \text{ papers per minute} \]

4. **Calculate the Average Papers Typed by One Typist**:
- Since there are 123 typists, we need to find out how many papers one typist types in a minute:
\[ \text{Papers typed by one typist per minute} = \frac{246 \text{ papers per minute}}{123 \text{ typists}} = 2 \text{ papers per minute} \]

### Final Answer:
The number of papers typed per minute by an average typist is **2**.
