Medium
In a company with 100 employees, 45 earn Rs. 20,000 per month, 25 earn Rs. 30,000, 20 earn Rs. 40,000, 8 earn Rs. 60,000, and 2 earn Rs. 150,000. The median of the salaries is
- ARs. 20,000
- Rs. 30,000
- CRs. 32,300
- DRs. 40,000
Explanation
With 100 values, the median is the average of the 50th and 51st sorted values. Cumulative counts: the first 45 employees earn 20,000 (positions 1-45); the next 25 earn 30,000 (positions 46-70). Both the 50th and 51st positions fall within the 30,000 group, so the median is 30,000.
