CAT 2008 — DILR Question 7

The gap between subscription revenues in US and Europe in 2003 = 420 – 105 = 315

The gap between subscription revenues in the US and Europe in 2004 = 525 – 180 = 345

∴ The percentage change in the gap between subscription revenues in the US and Europe in the period 2003-04 is

$\frac{345-315}{315}=\frac{30}{315}=\frac{2}{21}$

Similarly, the percentage change in the gap between subscription revenues in the US and Europe in the period 2005-06 is

$\frac{270-320}{320}=\frac{-50}{320}$

Hence, the absolute change is $\frac{5}{32}$

The percentage change in the gap between subscription revenues in the US and Europe in the period 2006-07 is

$\frac{220-270}{270}=\frac{-50}{270}$

Hence, the absolute change is $\frac{5}{27}$

The percentage change in the gap between subscription revenues in the US and Europe in the period 2008-09 is

$\frac{110-185}{185}=\frac{-75}{185}$

Hence, the absolute change is $\frac{15}{37}$

The percentage change in the gap between subscription revenues in the US and Europe in the period 2009-10 is

$\frac{100-110}{110}=\frac{-10}{110}$

Hence, the absolute change is $\frac{1}{11}$

The highest value among $\frac{2}{21},\frac{6}{33},\frac{5}{27},\frac{15}{37}$ and $\frac{1}{11}$ is clearly $\frac{15}{37}$

∴ The absolute value of change was the highest in the period 2008-09.

 Hence, option (d).
