A bowler took 15 wickets for 321 runs. What is his average score per wicket?

Answer

To find the average score per wicket taken by the bowler, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the total runs and total wickets**:
- Total runs scored by the bowler = 321 runs
- Total wickets taken by the bowler = 15 wickets

2. **Use the formula for average**:
- The formula to calculate the average score per wicket is:
\[ \text{Average score per wicket} = \frac{\text{Total runs}}{\text{Total wickets}} \]

3. **Substitute the values into the formula**:
- Substitute the total runs and total wickets into the formula:
\[ \text{Average score per wicket} = \frac{321}{15} \]

4. **Perform the division**:
- Now, divide 321 by 15:
- 15 goes into 32 two times (15 × 2 = 30), leaving a remainder of 2.
- Bring down the next digit (1), making it 21.
- 15 goes into 21 one time (15 × 1 = 15), leaving a remainder of 6.
- Add a decimal point and a zero to the remainder, making it 60.
- 15 goes into 60 four times (15 × 4 = 60), leaving a remainder of 0.
- Therefore, the result of the division is:
\[ 321 \div 15 = 21.4 \]

5. **Conclusion**:
- The average score per wicket taken by the bowler is **21.4 runs**.
