Explanation:

- To find the closing debtors, use the trade receivables turnover formula:

$$

\text{Trade Receivables Turnover Ratio} = \frac{\text{Net Credit Sales}}{\text{Average Debtors}}

$$

- Given that credit revenue is Rs2,40,000 and turnover ratio is 8 times.

$$

\text{Average Debtors} = \frac{2,40,000}{8} = 30,000

$$

- It's stated that closing debtors are Rs6,000 more than opening debtors.

- So, if Opening Debtors = x, then Closing Debtors = x + 6,000.

- The average debtors will be:

$$

\frac{(x + (x + 6,000))}{2} = 30,000

$$

- Which simplifies to:

$$

\frac{2x + 6,000}{2} = 30,000 \Rightarrow 2x + 6,000 = 60,000 \Rightarrow 2x = 54,000 \Rightarrow x = 27,000

$$

- Hence, Closing Debtors = 27,000 + 6,000 = 33,000.

Option 1: Rs33,000 – This is the correct answer.
