Madhya Pradesh Police Exam Model Paper 4

Given:
A library has an average of 265 visitors on Sundays and 130 visitors on other days.
Formula used:
Average Calculation:
Since the month begins with a Monday, to there will be four Mondays in the month.
${\mathit{M}}_1$ = Number of Sunday
${\mathit{M}}_1$ = 4
${\mathit{M}}_2$ = Remaining days
${\mathit{M}}_2$ = 26
${\mathit{N}}_1$ = Average visitors on Sundays
${\mathit{N}}_1$ = 265
${\mathit{N}}_2$ = Average visitors on Sundays
${\mathit{N}}_2$ = 130
Required average,
$\Rightarrow \left(265\mathit{x}4+130\mathit{x}26\right)/30$
$\Rightarrow 4440/30$
$\Rightarrow 148$
Therefore, The average number of visitors per day 148
