Correct answer: B
To find the median when the mean and mode are known, we use the empirical relationship formula: 3 × Median = 2 × Mean + Mode.
Substitute the given values: Mode = 15 and Mean = 30.
Calculate: 3 × Median = 2(30) + 15
Simplify: 3 × Median = 60 + 15 = 75
Solve for Median: Median = 75 / 3 = 25.
