Profit
Asked by | 8th Jan, 2010, 07:24: PM
Expert Answer:
Mean daily profit by a shopkeeper for 30 days = Rs. 350
Total profit of 30 days = 350 x 30 = Rs. 10500
Mean profit for first twenty days = Rs 400
Total profit of first twenty days = 400 x 20 = Rs. 8000
Total profit of remaining 10 days = Total profit of 30 days - Total profit of first twenty days
= 10500 - 8000 = Rs. 2500
Mean profit for last 10 days = 2500/ 10 = Rs 250
Hence the answer.
