D. 285
That month has 5 Sundays and 25 other days.
So, total visitors = 5*510 + 25*240 = 2550 + 6000 = 8550
Average visitors per day = 8550/30 = 285

D. 285

Explaination : Average of Visitors in Sunday, X = 510
Average of Visitors in Weekdays, Y = 240
Average of Visitors in a month of 30days, Z = ?
If the Month starts with Sunday means, it have 5 sundays and 25 week days.
Therefore, Z = (5X + 25Y)/30
(i.e) 5X = 5(510)
= 2550
24X = 24(240)
= 5760
Z = (2550+5760)/30
= 8310/30
= 285
