A grocer has a sale of Rs. 6435, Rs. 6927, Rs. 6855, Rs. 7230 and Rs. 6562 for 5 consecutive months. How much sale must he have in the sixth month so that he gets an average sale of Rs. 6500?
Show answer & explanation
Correct answer: C
Explanation
Sales for the first 5 months = ₹6,435, ₹6,927, ₹6,855, ₹7,230, ₹6,562
Total sales for 5 months = 6435 + 6927 + 6855 + 7230 + 6562 = ₹34,009
Average sales for 6 months = ₹6,500
Therefore, total sales for 6 months = 6500 × 6 = ₹39,000
Sales for the sixth month = 39000 − 34009 = ₹4,991
