Question

In a particular week the average number of people visited the museum is $70.$ If we exclude the holidays then the average number is increased by $28$. Further if we exclude the day which the maximum of $210$ visitors visited the museum, then the average become $40$.Find the no of holidays in the week

Answer 1

Total no of visitors in a week $=70\times 7=490$

Let $x=$ no of holidays

Exclude hloidays

$\Rightarrow (7-x)\times 98=490$

$\Rightarrow 7-x=5$

$\therefore x=2$
