Question

A store offers four different brands of a product. It decides to eliminate thebrand that is most likely to be returned. The table shows the number of itemsof each brand that were returned over the past year and the total sold.Brand ABrand BBrand CBrand DReturns33152932Which brand should the store eliminate?Total sold686492362767

Answer 1

To find which brand is more likely to be returned, we cannot simply look at the 'Returns' column. We must find the unit ratio of the returns with respect to the units sold.

Calculating each ratio:

$\begin{gathered} \frac{33}{686}=0.048 \\ \\ \frac{15}{492}=0.03 \\ \\ \frac{29}{362}=0.08 \\ \\ \frac{32}{767}=0.042 \end{gathered}$

We can see Brand C has a higher ratio of returns, so it should be the one to be eliminated from stock.

C. Brand C
