Read Solution (Total 3)
-
- The total salary amount = 15 * 600 = 9000
The salary of the exiting manager = 720.
Therefore, the salary of 12 workers and the remaining 2 managers = 9000 - 720 = 8280
When a new manager joins, the new average salary drops to Rs.580 for the total team of 15 of them.
The total salary for the 15 people i.e., 12 workers, 2 old managers and 1 new manager = 580 *15 = 8700
Therefore, the salary of the new manager is 9000 - 8700 = 300 less than that of the old manager who left the company, which is equal to 720 - 300 = 420. - 12 years agoHelpfull: Yes(24) No(0)

- 12 workers and 3 managers
12+3=15 *600=9000
9000-720=8280( Total salary of 14 members)
12+3=15*580=8700(Total salary of 15 members)
Salary of new person=8700-8280=420.
