Correct Answer

✅ Option b — 2

All Options:

  • A3
  • B2
  • C23\displaystyle \frac{2}{3}
  • D32\displaystyle \frac{3}{2}

Detailed Solution & Explanation

**Step 1: Given information.** Let Mean = μ\displaystyle \mu, Median = 2μ\displaystyle 2\mu (given), and let Mode = M\displaystyle M. **Step 2: Apply the empirical formula.** Mode=3×Median−2×Mean\text{Mode} = 3 \times \text{Median} - 2 \times \text{Mean} M=3(2μ)−2μ=6μ−2μ=4μM = 3(2\mu) - 2\mu = 6\mu - 2\mu = 4\mu **Step 3: Express Mode as multiple of Median.** MMedian=4μ2μ=2\frac{M}{\text{Median}} = \frac{4\mu}{2\mu} = 2 So Mode = 2×\displaystyle 2 \times Median. Hence, **Option B** is the correct answer.
