- AThe mean and the median are equal
- BThe median is greater than the mean, because the value 92 raises the middle salary
- CThe mean is less than the median, because most of the salaries are small
- DThe mean is greater than the median, and only one employee earns more than the mean
Step-by-Step Solution
The middle value of the 7 ordered salaries is 24, so the median is ₹24 thousand. The mean is (18 + 20 + 22 + 24 + 26 + 28 + 92) ÷ 7 = 230 ÷ 7 ≈ 32.9 thousand, which is above every salary except 92 — so exactly one employee earns more than the mean. One extreme value pulls the mean upwards but leaves the median exactly where it was, which is why the median describes a typical salary here far better.
Answer: D) The mean is greater than the median, and only one employee earns more than the mean
