A line of length 1.5 metres was measured as 1.55 metres by mistakes. What will be the value of error percent ?

Answer: Option C

Percentage error :
= $$\frac{1.55-1.50}{1.50}$$   × 100
= $$\frac{0.05}{1.50}$$ × 100
= $$\frac{5}{150}$$ × 100
= $$\frac{5\times 2}{3}$$
= $$\frac{10}{3}$$
= $$3\frac{1}{3}$$%
