Question
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?Rs. 4991Rs. 5991Rs. 6001Rs. 6991
Solution
To find out how much sale the grocer must have in the sixth month to get an average sale of Rs. 6500, we first need to calculate the total sale for the first five months and the total sale needed for six months to have an average of Rs. 6500.
Step 1: Calculate the total sale for the first five months. 6435 + 6927 + 6855 + 7230 + 6562 = Rs. 34,009
Step 2: Calculate the total sale needed for six months to have an average of Rs. 6500. 6500 * 6 = Rs. 39,000
Step 3: Subtract the total sale of the first five months from the total needed for six months to find out how much sale the grocer must have in the sixth month. 39,000 - 34,009 = Rs. 4,991
So, the grocer must have a sale of Rs. 4,991 in the sixth month to get an average sale of Rs. 6500. Therefore, the correct answer is Rs. 4991.
