Answer:

(c) Rs.23,220

Step-by-step explanation:

Average = Sum of observations / No. of observations

Sum of observations = Average * No. of observations

Given

Average sales for all six working days = Rs.15640

=> Total sales for all six working days  = 6*15640 = Rs,93840 ..(i)

Average sales for five days (Tue to Sat) = Rs.14124

=> Total sales for five days (Tue to Sat) = 5*14124 = Rs.70620 ...(ii)

Clearly, (i) - (ii) will give us sales on the remaining day, which is Sunday.

Sales of Sunday = 93840 - 70620

                            = 23220

Sales on Sunday = Rs.23,220 [Given as Option (c)]
