Explanation:
The total sales for the first 5 months are Rs. 6435, Rs. 6927, Rs. 6855, Rs. 7230, and Rs. 6562, which sum to Rs. 34,909.
To achieve an average of Rs. 6500 over 6 months, the total sales for 6 months must be Rs. 39,000 (6500 * 6).
Therefore, the sale needed in the sixth month is Rs. 39,000 - Rs. 34,909 = Rs. 4991.
So, the correct answer is Rs. 4991.
