Answer:23220
Step-by-step explanation:
Description for Correct answer:
According to the question,
Total sales for remaining 6 days (Sun + Tue + Wed + Th + Fri + Sat) = 15640×6
= 93840 Rs. .......(i)
Total sales from tuesday to saturday (Tue + Wed + Thr + Fri + sat) = 14124×5
= 70620 Rs. ......(ii)
=> After subtracting eq. (i) - (ii)
=> The sale on sunday is = 93840 - 70620 = 23220 Rs.
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)]
