- ARs. 4,991
- BRs. 5,021
- CRs. 4,810

Solution & Step-by-step Explanation
To achieve an average sale of Rs. 6,500 over 6 months, the total sales required is:
Total Sales=6×6500=Rs. 39,000
The sum of sales for the first 5 months is:
Sum of 5 months=6435+6927+6855+7230+6562=Rs. 34,009
Therefore, the required sales in the sixth month is:
Sales in 6
th
month=39000−34009=Rs. 4,991
Total Sales=6×6500=Rs. 39,000
The sum of sales for the first 5 months is:
Sum of 5 months=6435+6927+6855+7230+6562=Rs. 34,009
Therefore, the required sales in the sixth month is:
Sales in 6
th
month=39000−34009=Rs. 4,991
