• A. ₹14,750
• B. ₹13,000
• C. ₹13,750
• D. ₹13,500

Answer 1

Answer:

C. ₹13,750

The average salary of the 8 employees is ₹13,750.

1. Find total people

The group consists of $8$ employees and $1$ supervisor.
$\text{Total people} = 8 + 1 = 9$

2. Calculate total salary

Multiply the total number of people by their combined average salary.
$\text{Total salary} = 9 \times 15,000 = 1,35,000$

3. Subtract supervisor's salary

Deduct the supervisor's earnings from the total salary to find the portion belonging only to the employees.
$\text{Employees' total salary} = 1,35,000 - 25,000 = 1,10,000$

4. Find employees' average

Divide the employees' total salary by the $8$ employees.
$\text{Employees' average salary} = \frac{1,10,000}{8} = 13,750$

Final Answer

The average monthly salary of the 8 employees is ₹13,750.
