Fifteen movie theatres average 600 customers per theatre per day. If six of the theatres close down but the total theatre attendance stays the same, then the average daily attendance per theatre among the remaining theatres is
-
- 900
- 1000
- 1100
- 1200
- 900
Correct Option: B
Given that , Average number of customers in 15 movie theatres = 600
Total number of customers in 15 movie theatres = 15 × 600 = 9000
∴ Required average number of customers = 9000 ÷ 9 = 1000
