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 Sunday is:

1250
2276
3280
4285

Answer:- 1

Explanation:-

Solution:

Since the month begins with a Sunday, to there will be five Sundays in the month.

\begin{aligned} ∴ Required average \\ = (\frac{510 \times 5 + 240 \times 25}{30}) \\ = \frac{8550}{30} \\ = 285 \end{aligned}

$\eqalign{ & \therefore {\text{Required}}\,{\text{average}} \cr & = \left( {\frac{{510 \times 5 + 240 \times 25}}{{30}}} \right) \cr & = \frac{{8550}}{{30}} \cr & = 285 \cr}$
