Answer
Correct Answer: None of these
Explanation
### Concept & Averages
First, find the total number of books distributed by calculating the given percentage of the total published books. Then, divide this amount evenly among the number of distributors.
$$ \text{Books per Distributor} = \frac{\text{Total Distributed Books}}{\text{Number of Distributors}} $$
### Step-by-Step Solution
1. **Find Total Books Distributed by Q:**
- Total Published = $33800$
- Distribution Percentage = $79\%$
- Distributed Books = $33800 \times \left(\frac{79}{100}\right) = 338 \times 79$
- $338 \times 79 = 26702$
2. **Divide Equally Among Distributors:**
- Number of distributors in Q = $25$
- Books per distributor = $\frac{26702}{25} = 1068.08$
3. **Analyze the Result:**
- Since $1068.08$ is not an integer, the books cannot be distributed *perfectly* equally without a remainder. Therefore, none of the exact integer options accurately reflect an "equal" mathematical distribution.
### Exam Strategy & Shortcut
To quickly multiply $338 \times 79$, use $338 \times (80 - 1) = 27040 - 338 = 26702$. Dividing by $25$ is the same as multiplying by $4$ and dividing by $100$: $26702 \times 4 = 106808 \rightarrow 1068.08$. Observing the decimal indicates that the integer option 1068 is technically incomplete.
### Common Pitfall
Choosing option (b) 1068 by ignoring the decimal/remainder. In rigorous aptitude exams, if an exact division is implied ("equal number") and yields a decimal fraction for discrete objects like books, "None of these" is the mathematically correct choice.
### Final Answer
Therefore, the correct answer is **None of these**.
