Direction : Study the following table and answer the questions that follow : Number of employees and monthly salary per employee in five departments of a companyDepartment Number of Employees Monthly Salary per Employee (₹) HR 40 45,000 Finance 30 60,000 Marketing 50 36,000 Administration 60 40,000 IT 20 75,000
The company’s total monthly salary expenditure on HR, Finance and Marketing combined is what fraction of the company’s total monthly salary expenditure on all five departments ?
\( \frac{18}{31} \)
HR = \( 40 \times 45000 = 1800000 \), Finance = \( 30 \times 60000 = 1800000 \), Marketing = \( 50 \times 36000 = 1800000 \).
Combined = \( 1800000 \times 3 = 5400000 \) and the total for all five departments = ₹ 93,00,000.
Required fraction = \( \frac{5400000}{9300000} = \frac{54}{93} = \frac{18}{31} \).
Check: \( \frac{18}{31} \times 9300000 = 5400000 \).
Hence, \( \frac{18}{31} \).
