Answers
Answer:
900 is the correct answer
Step-by-step explanation:
Given:
Average salary of 12 operators and 3 managers is Rs 830
One manager whose salary is Rs 900 is replaced by another manager.
The new average salary is now Rs 800
To Find:
Salary of the new manager
Solution:
Find the total salary of the old team:
Total number of staff = 12 + 3
Total number of staff = 15
Average salary = Rs 830
Total salary = 15 x 830
Total salary = Rs 12450
Find the total salary of the new team:
Total number of staff = 12 + 3
Total number of staff = 15
Average salary = Rs 800
Total salary = 15 x 800
Total salary = Rs 12000
Find the new manager's salary:
15 operators with 3 managers (with old manager) = Rs 12450
15 operators with 3 managers (with new new manager) = Rs 12000
150 operators with 2 managers (without old manager) = 12450 - 900
150 operators with 2 managers (without old manager) = 111550
New manager's pay = 12000 - 11550
New manager's pay = Rs 450
Answer: The new manager is paid Rs 450
