Calculate and correct to two significant figures, the percentage error in approximating 0.375 to 0.4
  • A.
    2.0
  • B.
    2.5
  • C.
    6.6
  • D.
    6.7
Correct Answer: Option D
Explanation

Measured value = 0.375
Approximation = 0.4
Error = 0.4 – 0.375 = 0.025
Error% = (frac{0.025}{0.375}) x 100% = 6.67% = 6.7%
