$\text{Study the given graph and answer the question that follows.}$

$\text{The following bar graph shows the strength of employees (in lakhs) in a company during five different years.}$

$\text{What was the percentage increase in employees in}2022\text{ over}\mathrm{ 2019}?$

The correct answer is 75%.


From the given bar graph showing the strength of employees (in lakhs) in a company during five different years:
• Number of employees in 2019 = 20 lakhs
• Number of employees in 2022 = 35 lakhs

Step 1: Calculate the increase in the number of employees from 2019 to 2022.
$\text{Increase in employees}=\text{Employees in 2022}-\text{Employees in 2019}$
$\text{Increase in employees}=35-20=15\text{ lakhs}$

Step 2: Calculate the percentage increase over 2019.
The formula for percentage increase is:
$\text{Percentage Increase}=\left(\frac{\text{Increase in employees}}{\text{Employees in 2019}}\right)\times 100$
Substituting the corresponding values:
$\text{Percentage Increase}=\left(\frac{15}{20}\right)\times 100$
$\text{Percentage Increase}=0.75\times 100=75\text{\%}$

Thus, the percentage increase in employees in 2022 over 2019 is 75%.
