Problem

Last year Mr. Jon Q. Public received an inheritance. He paid 20% in federal taxes on the inheritance, and paid 10% of what he had left in state taxes. He paid a total of $10500 for both taxes. How many dollars was his inheritance?

Solution

After paying his taxes, he has $.8*.9=.72$ of the inheritance left. Since 10500 is .28 of the inheritance, the whole inheritance is $\frac{10500}{0.28}=37500\  \mathrm{(D)}$.
