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).

In 2008, we see that sales are 753, and that half those sales - 753/2 = 376.5 - are due to the 2007 investment in R&D. We can use the percent change formula:

(376.5 - 75)/75 x 100 = 301.5/75 x 100 ≈ 300/75 x 100 = 400 percent, which is closest to 402%.

Answer: D
