Correct Answer - Option 2 : 25%

**GIVEN:**

Standard Deviation = 6

Mean of the distribution = 24

**FORMULA USED:**

Standard Deviation = Mean × Co-efficient of Variance/100

**CALCULATION:**

Standard Deviation = Mean × Co-efficient of Variance/100

⇒ 6 = 24 × Co-efficient of Variance/100

⇒ Co-efficient of Variance = 100/4 = 25%

**∴ Co-efficient of Variance = 25%**
