Directions (56-60) : Read the bar graph carefully and answer the following questions.

The bar graph given below shows the no. of employees working from Office and percentage of employees working from home out of total employee in five different companies.

Number of employees working in any company = Employees working from Office + Employees working from Home

Find the ratio of number of employees working from Home in company E to that in company C.

The correct option is 10: 1.

From the given bar graph, we can observe the following data for different companies regarding employees working from the office and the percentage of employees working from home:

For Company C:
Number of employees working from Office = 180
Percentage of employees working from Home = 40%

Let the total number of employees in company C be $T_C$.
Since 40% of employees work from Home, the percentage of employees working from Office is:

$100\%-40\%=60\%$

Therefore:

$60\%\text{ of }{T}_C=180$

$T_C=\frac{180\times 100}{60}=300$

Number of employees working from Home in company C:

$=40\%\text{ of }300=120$

For Company E:
Number of employees working from Office = 300
Percentage of employees working from Home = 80%

Let the total number of employees in company E be $T_E$.
Since 80% of employees work from Home, the percentage of employees working from Office is:

$100\%-80\%=20\%$

Therefore:

$20\%\text{ of }{T}_E=300$

$T_E=\frac{300\times 100}{20}=1500$

Number of employees working from Home in company E:

$=80\%\text{ of }1500=1200$

Finding the required ratio:
Ratio of number of employees working from Home in company E to that in company C:

$=\frac{1200}{120}=\frac{10}{1}$

Thus, the required ratio is 10: 1.
