Line graph shows number of departments and average number of employees in all the departments in five different companies (P, Q, R, S and T). Read the following line graph carefully and answer the questions given below.

Total number of employees in all the departments of company P is what percent more or less than that of company R.

The correct answer is 31.25%.

From the given line graph, we can observe the following data for each company:

• Blue line: Number of departments
• Orange line: Average number of employees in all departments

Step 1: Calculate the total number of employees in company P.

For Company P:
• Number of departments = 15
• Average number of employees per department = 35

Total employees in Company P = Number of departments × Average number of employees per department

$\text{Total employees in P}=15\times 35=525$

Step 2: Calculate the total number of employees in company R.

For Company R:
• Number of departments = 10
• Average number of employees per department = 40

Total employees in Company R = Number of departments × Average number of employees per department

$\text{Total employees in R}=10\times 40=400$

Step 3: Calculate the percentage by which total employees in P are more than that of company R.

Difference in total employees = 525 - 400 = 125

Percentage more:

$\text{Percentage More}=\left(\frac{525-400}{400}\right)\times 100$

$\text{Percentage More}=\left(\frac{125}{400}\right)\times 100=\frac{125}{4}=31.25\%$

Thus, the total number of employees in company P is 31.25% more than that of company R.
