Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 260.
In a month of 30 days, if the first day is Sunday then there will be 5 Sundays in the month.
According to the given question,
Total attandance on Sundays = 5 × 410
⇒ 2050
Total attendance on remaining days of the month = 25 × 230
⇒ 5750
Total attendance of the month = 2050 + 5750 = 7800
Average attendance per day = 7800/30 = 260
