Explanation:

Step1: Calculate total salary

Multiply each salary by its frequency and sum them:
\(23000\times4 + 26000\times3 + 30000\times2 + 45000\times1\)
\(= 92000 + 78000 + 60000 + 45000\)
\(= 275000\)

Step2: Calculate total employees

Sum the frequencies: \(4 + 3 + 2 + 1 = 10\)

Step3: Find the mean

Divide total salary by total employees: \(\frac{275000}{10} = 27500\)

Answer:

\(27500\)
