Answer»

Now as the FORMULA for AVERAGE can be given as

AE = SE/NE

Where AE = Average of entities

SE = Sum of entities

NE = Number of entities

Now as the average sales per day for remaining six days of a week are RS. 13640

∴ Sum of sales of six days = 13640 × 6 = 81840 Rs.

Now as the average sale of Tuesday to Thursday is Rs. 15152

∴ Sum of sales of Tuesday to Thursday = 15152 × 3 = 45456 Rs.

Now as average sales of Friday to Saturday is Rs. 8726

∴ Sum of sales of Friday to Saturday = 8726 × 2 = 17452 Rs.

Now the sales of SUNDAY can be given as

Total sales of six days - sales of Tuesday to Thursday - sales of Friday to Saturday

= 81840 - 45456 - 17452

= Rs. 18932
