Management Aptitude Test Sep 2020 Paper

The production of Company $\mathit{R}$ to production of Company $\mathit{Q}$ in the year 2010
$=\frac{\left(70+80\right)-\left(50+70\right)}{\left(70+50\right)}\times 100\%$
$=\frac{30}{120}\times 100\%=25\%$
In the year $2011=\frac{\left(70+90\right)-\left(70+80\right)}{\left(70+80\right)}\times 100\%$
$=\frac{10}{150}\times 100\%=\frac{20}{3}\%$
In the year $2012=\frac{\left(80+70\right)-\left(70+90\right)}{\left(70+90\right)}\times 100\%$
$=\frac{-10}{160}\times 100\%$
$=\frac{-25}{4}\%$
In the year $2013=\frac{\left(70+100\right)-\left(80+70\right)}{\left(80+70\right)}\times 100\%$
$=\frac{20}{150}\times 100\%$
$=\frac{40}{3}\%$
From above, we can say that the percentage of production of Company $\mathit{R}$ to production of Company $\mathit{Q}$ is the maximum in the year 2010 .
