A student measured the height of a pole as 5.98 m which is less than the actual height. If the percentage error is 5%, find, correct to two decimal places, the actual height of the pole.
- A. 6.65 m
- B. 7.67 m
- C. 6.29 mCorrect
- D. 6.65 m
Explanation
% error=(x-5.98)/x×100=5 → 5x=100(x-5.98) → 5x=100x-598 → 95x=598 → x=6.29 m.
