Money invested in 2007(in R&D) is 75
Since the sales remains the same in 2008 and half of this
sales are due to the R&D investment, the amount must be \(\frac{753}{2}\)
Percentage -> \(\frac{753}{2}*\frac{1}{75}*100 = \frac{1506}{3} = 502\)
Since we have been asked to find by how much percent was the revenue recovered by
sales will be greater than the money invested in R&D, it must be 402%(Option D)

Another approach, using easier numbers because the answer values are far apart:
1) Sales in 2008 (not shown) are the same as sales in 2007. Sales in 2008 = 753
2) Half of 2008 sales = ?*
2008 sales = 753\(\approx{754}\)
\(\frac{754}{2}= 377\)
3) The revenue received from half of sales is what percent greater than amount invested in 2007 R&D?
Amount invested in R&D = 75
2008, half of sales, 377\(\approx{375}\)
"Percent greater than" = Percent change =
\(\frac{New-Old}{Old} * 100\)
\(\frac{375-75}{75}*100=\frac{300}{75}*100= 4*100 = 400\) %
Answer D
* This information is unnecessary: ". . . half of those [2008] sales are directly due to the 2007 investment in R&D." If the question were to ask about return on investment, then the source of half the 2008 sales would matter. Here, we just need half of 2007's sales (753).
