Given : There are 35 workers in a company.
Each of 17 workers earns Rs. 3,000 per year;
each of 11 workers earns Rs. 4,000 yearly;
each of 4 workers earns Rs. 6,000 yearly;
each of 2 workers earns Rs. 7,000 yearly and
the remaining workers earn Rs. 10,000 yearly.
To Find : the A.M and the Median of the earned income.
Solution:
Earning x f cf fx
3000 17 17 51000
4000 11 28 44000
6000 4 32 24000
7000 2 34 14000
10000 1 35 10000
35 143000
Median = (35 + 1)/2 = 18th
18 lies in 4000
Hence Median = 4000
AM = 143000/35 = 4,085.71
Median = 4000 Rs
AM = 4,085.71 Rs
