Question

If a car factory checks 380 cars and 11 of them havedefects, how many will have defects out of 1260 cars?

Answer 1

Answer:

Explanation:

Let x represent the number of defective cars.

Assuming that number of defective cars are uniformly distributed in the total number of cars, we can go ahead and solve for x by setting up proportion as shown below;

$\begin{gathered} \frac{11}{380}=\frac{x}{1260} \\ 380x=13860 \\ x=\frac{13860}{380} \\ x=40 \end{gathered}$
