getsGiven data:

Let A =Total number of problem test Krubasoe takes = 40

B= number Krubasoe gets correct = 37

C= number Kurbasoe gets incorrect = (A - B) = 40 - 37 = 3

Hence, %problems she get incorrect will be


\begin{gathered} =\text{ }\frac{\text{number she gets incorrect }}{\text{total number of problem test}}*100\text{ \%} \\ =(3)/(40)*100\text{ \%= 7.5\%} \end{gathered}

Therefore, the percent of problems she gets incorrect is 7.5%
