Hint: We have to find a reading error in percent. For which first we have to find error in reading then we will find the percentage of it by formula. Percentage error = $\dfrac{{{\text{error}}}}{{{\text{correct number}}}} \times 100$

Percentage error = $\dfrac{{{\text{error}}}}{{{\text{correct number}}}} \times 100$
Percentage error = $\dfrac{{18}}{{42}} \times 100 = 42.8\%$
