Answer & Solution
Correct answer: A.
1. List incomes in increasing order: 16500, 17000, 17500, 18000, 18600, 19500, 21000, 21050, 21700, 22000, 175000.
2. With 11 values, the median is the middle (6th) value.
3. Sixth value in order is 19 500.
4. So the median is 19 500 rupees.
5. Unlike the mean, the median is barely affected by the outlier of 175 000.
