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%
