In a small snack shop, the average (arithmetic mean) revenue was $400 per day over a 10-day period. During this period, if the average daily revenue was $360 for the first 6 days,
what was the average daily revenue for the last 4 days?
D. $460 is my answer.
400 = x/10
x = 4000
For first 6 days = 360 * 6 = $2160
therefore for the last 4 days revenue is $4000 - $2160 = 3840
hence, airthmatic mean = 3840/4 = $460
Please let me know the OA.
