Correct answer: D
Correct Option
Option D: 25
Step-by-Step Solution
Understand the Formula:
The empirical relationship between the three measures of central tendency is: Mode = 3 * Median - 2 * Mean.
Substitute the Given Values:
Mode = 15.
Mean = 30.
Substituting into the formula: 15 = 3 * Median - 2 * 30.
Solve for the Median:
15 = 3 * Median - 60.
Add 60 to both sides: 15 + 60 = 3 * Median.
75 = 3 * Median.
Median = 75 / 3 = 25.
