Question 133

A shop of electronic goods is closed on Monday. The average sales per day for remaining six days of a week is Rs.15640 and the average sale of Tuesday to Saturday is Rs.14124. The sales on Sunday is:

Solution

We know that average = sum of entries/no of entries

Therefore given average of 6 days = 15640

i.e;sum of entries/6=15640

so sum=15640*6=93840.

also given the average sales from tuesday to saturday i.e;5 days is

sum of 5 days' sales/5=14124

therefore sum of 5 day sales=5*14124=70620

sales on sunday is (sum of 6 days sale)-(sum of 5 day sale)

i.e; 93840-70620=23220.

Therefore the answer is 23220.
