Question

If Operating Profit is defined as Revenue - Expenses and OPM (Operating Profit Margin) as the Operating Profit as a percentage of Revenue, then which of the following statements is true?

Options:

A . The OPM for 1999 was greater than that for 2000

B . The OPM for 2000 was greater than that for 1999

C . The OPM for year 1999 and 2000 was equal

D . Data insufficient

Answer: Option B
:
B

Conventional Approach

Here we have to compare the ratios 5184/13386, 2318/6049, i.e. we have to compare 51.84% of 6049 and 23.18% of 13386.

50% of 6049 is 3024.5; 1% of 6049 is 60.49; 0.8% of 6049 is 48.392; 0.05% of 6049 is 3.0245. Thus, 51.85% of 6049 is 3024.5 + 60.49 + 48.392 + 3.02 = 3136.4.

Similarly, 20% of 13386 is 2677.2; 3% of 13386 is 401.58; 0.1% of 13386 is 13.386, and 0.08% is 10.708 and thus 23.18% of 13386 is 2677.2 + 401.58 + 13.38 + 10.70 = 3102.86.

Thus, the first ratio is greater and thus OPM of 2000 is greater than that for 1999.

Shortcut

Cut down the number of digits. (OPM)99 $= \frac{13 - 8}{13} = \frac{5}{13}$ and (OPM)2000 $= \frac{6 - 3}{3} = \frac{3}{6}$ or $\frac{1}{2}$ . Thus you can directly see that $\frac{1}{2}$ is greater than $\frac{5}{13}$ .
