Management Aptitude Test 2014 Paper

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