Correct Answer

✅ Option a — 50.85

All Options:

  • A50.85
  • B34.43
  • C52.65
  • D51.85

Detailed Solution & Explanation

We are given: - Mean deviation about Arithmetic Mean: M.D.=1.78\displaystyle \text{M.D.} = 1.78 - Arithmetic Mean: xˉ=3.50\displaystyle \bar{x} = 3.50 The coefficient of mean deviation about mean is defined as: Coefficient of M.D.=M.D.xˉ×100\text{Coefficient of M.D.} = \frac{\text{M.D.}}{\bar{x}} \times 100 Coefficient of M.D.=1.783.50×100≈50.85%\text{Coefficient of M.D.} = \frac{1.78}{3.50} \times 100 \approx 50.85\% Hence, **Option A** is the correct answer.
