Answer 1

Answer:

The sales for Sunday is 570 units.

Explanation:

From the above question, the average sales of a product for a particular week, excluding Sunday, were reported to be as 150 units.

Sunday, being a national festival, there was heavy rush of sales which inflated average sales for the entire week to 210 units.

Total Number of Days excluding Sunday = 6

Let x = Total Sale of Product for a week excluding Sunday

Here we need to find, the sales for Sunday. :

x/6 days =Average Sales of Product

x/6 = 150

x = 150 units * 6 days = 900 units for 6 days

For entire week (7 days),

Total sales = average sales for entire week x 7 days

Total Sales = 210 units x 7 days = 1470 units

Sale for Sunday = Total sales for entire week - Total sales for week except Sunday

Sale for Sunday = 1470 units - 900 units = 570 units

Hence, 570 units are sold for Sunday.
