The trick to solving this problem is to understand that the re-investment
in the business is 10% of the remainder and not of the whole.


The remainder after 40% of the total amount is 60, whose 10% is 6.
Therefore, the amount re-invested in the business is 6% of 2000 or \(0.6*2000 = $120\)(Option D)

We see that his business expenses are 2,000 x 0.4 = $800. Therefore, the remainder is $1,200, and 10 percent of that is 1,200 x 0.1 = $120. Thus, $120 is reinvested in the business.

Answer: D
