A. 276 B. 280 C. 285 D. 250 Answer: Option CShow Answer
Solution(By Apex Team)
If a month beings with Sunday then there are 5 Sundays in that month.
Total number of visitors comes on Sunday
= 510 × 5 = 2550
Total number of visitors come on other days
= 240 × 25 = 6000
∴ Average number of visitor per day
$\begin{array}{l}
=\Large\frac{2550+6000}{30} \\
=\Large\frac{8550}{30} \\
=285
\end{array}$
