A library has an average of 510 visitors on Sundays and 240 on other days. The average number of visitors per day in a month of 30 days beginning with a Saturday is

- 250
- 276
- 280
- 285

**Answer: (4) 285**

**Solution:-**

The average visitors on Sunday = 510

The number of Sunday in 30 days if beginning with Sundays = 5

Total visitors on Sunday in 30 days = 5 x 510

= 2550

The number of remaining other days = 25

The average visitors on other days = 240

Then, the total visitors on other days = 240 x 25

= 6,000

Total visitors in a month = 6,000 + 2550

= 8,550

The average of visitors in month of 30 days = 8,550/30

= 285

Hence, the correct answer is option (4) 285.
