Anand has drawn an angle of measure 45° 27' when he was asked to draw an angle of 45° . The percentage error in his drawing is ?

A. 0.5%

B. 1%

C. 1.5%

D. 2.0%

Answer: Option B

Solution(By Examveda Team)

Error = (45° 27' - 45° ) = 27'
Accurate measure = 45° = (45 × 60)' = 2700'
∴ Percentage error :
$$\eqalign{ & = \left( {\frac{{27}}{{2700}} \times 100} \right)\% \cr & = 1\% \cr} $$
