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 $\begin{array}{l} =\Large\frac{2550+6000}{30} \\ =\Large\frac{8550}{30} \\ =285 \end{array}$
