The table given here shows production of five types of cars by a company in the year $2010$ to $2015$. Study the table and answer the question. 

$\textbf{Production of Cars by a Company}$

$\begin{array}{|cl|cI|cI|cI|cI|cI|}\hline
&\text{Year/Type} & \text{2010} & \text{2011} & \text{2012} & \text{2013} & \text{2014} & \text{2015} & \text{Total} \\ \hline &\text{P} & \text{8} & \text{20} & \text{16} & \text{17} & \text{21} & \text{6} & \text{88} \\ \hline &\text{Q} & \text{16} & \text{10} & \text{14} & \text{12} & \text{12} & \text{14} & \text{78}\\ \hline

The production of which type of cars was $25\%$ of the total production of all types of cars during $2014$?

• A. $S$
• B. $R$
• C. $Q$
• D. $P$

Answer 1

Option A

$25 \% * 80 \Rightarrow 20 \Rightarrow S$

Answer 2

In $2014:S = \dfrac{20}{80} \times 100\% = 25\%$

In $2014:R = \dfrac{13}{80} \times 100\% = 16.25\%$

In $2014:S = \dfrac{12}{80} \times 100\% = 15\%$

In $2014:S = \dfrac{21}{80} \times 100\% = 26.25\%$

$\therefore$ The production of $S$ type of car was $25\%$ of the total production of all types of cars during $2014.$

So, the correct answer is $(A).$
