A library has an average of 330 visitors on Sundays and 240 on the other days. Find the average of the number of visitors per day in a month of 30 days, beginning with a Saturday.
Answer & explanation
Correct answer: option 2
In a month of 30 days started with saturday , Total number of Sunday = 5
Normal days = 25
Total number of visitors on Sunday = 5 × 330 = 1650
Total number of visitors on Normal day = 25 × 240 = 6000
Average of visitors in 30 days = \(\frac{1650 + 6000}{30}\)
= \(\frac{7650}{30}\) = 255
