Average salary of 17 teachers is 45000.3 teachers left and the average salary dropped by 2500.What is the sum of salaries of 3 teachers who left?

Answer

Total Initial Salary : 17*45000 = 765000

Average Salary After removal of 3 Teachers = 45000-2500 = 42500

Total Final Salary : 14*42500 = 595000

Sum of Salaries of 3 teachers who left : 765000 - 595000 = 170000

Solution 2:

let x be the sum of salary

given x/17=45000

x=765000

if 3 left

x/14=42500

x=595000

prev avg - new avg=765000-595000 = 170000
