The average monthly
salary of 12 workers and 3 managers in a factory was Rs. 600. When one of the
manager whose salary was Rs. 720, was replaced with a new manager, then the
average salary of the team went down to 580. What is the salary of the new
manager?
a) 420
b) 570
c) 690
d) 620
e) None.
Answer: Option a
ReplyDeleteExplanation:
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
