If coefficient of variation is \( 60 \) and standarddeviation is \( 24 \), then Arithmetic mean is
- A \( 40 \)
- B \( \frac{7}{20} \)
- C \( \frac{20}{7} \)
- D \( \frac{1}{40} \)
Answer & Solution
Correct Answer
(A) \( 40 \)
Step-by-step Solution
Detailed explanation
Coefficient of variation is given by
\[
C V=\frac{\sigma}{x} \times 100
\]
Here, \( \mathrm{CV}=60 \) and \( \sigma=24 \). Then,
\[
C V=\frac{\sigma}{x} \times 100
\]
Here, \( \mathrm{CV}=60 \) and \( \sigma=24 \). Then,
