Estimated Profit = Estimated Revenue - Estimated Cost
Actual Profit = Actual Revenue - Actual Cost

For how many years, actual profit is more than estimated profit?

  • A.0
  • B.1
  • C.2
  • D.3

Answer: C

Actual profit exceeds estimated profit in 2 years.

\[ \begin{aligned} \text{Est.} &: 295,\ 401,\ 204 \\ \text{Actual} &: 338,\ 210,\ 384 \end{aligned} \]

Each figure is revenue minus cost for 2007, 2008 and 2009. For example, the 2007 estimate is \(1281 - 986 = 295\) and the 2007 actual is \(1326 - 988 = 338\).

Actual profit is higher in 2007 (338 against 295) and in 2009 (384 against 204), but lower in 2008 (210 against 401), because actual sales in 2008 fell short of the estimate while costs ran over. So the count is two, not one or three.
