Management Aptitude Test 2015 Paper

(b) Percentage of rise / fall in production from the previous for company B
From 2009 to 2010
= $\frac{60-50}{55}$ × 100
= $\frac{5}{55}$ × 100
= 9.09% (rise)
From 2010 to 2011
= $\frac{50-60}{60}$ × 100
= $-\frac{10}{60}$ × 100
= -16.66% (fall)
From 2011 to 2012
= $\frac{55-50}{50}$ × 100
= $\frac{5}{50}$ × 100
= 10% (rise)
From 2012 to 2013
= $\frac{50-55}{55}$ × 100
= $-\frac{5}{55}$ × 100
= - 9.09% (fall)
From 2013 to 2014
= $\frac{55-50}{50}$ × 100
= $\frac{5}{50}$ × 100
= 10% (rise)
So, year 2011 shows the maximum percentage fall in the production from the previous year for company B.
Hence, option (b) is correct.
