Question

The mean salary of 20 workers is Rs.10,250. If the salary of office superintendent is added, the mean will increase by Rs.750. Find the salary of the office superintendent.

Answer 1

Answer:

26000

Step-by-step explanation:

total salary of 20 workers= (20*10250)

now increase in mean of 750 is (10250+750) ie 11000

and workers are (20+1) ie 21.

Now difference in salary is (11000*21)- (10250*20) = 26000.

which is the salary of office superintendent.

Hope it helps.
