After taking several practice tests, Brian improved the results of his GRE test by 30%. Given that the first time he took the test Brian had answered 150 questions correctly, how many correct answers did he answer in the second test?

The first time, Brian answered 150 questions correctly and the second time he answered $30 \%$ more correctly, so, $150+(30 / 100 * 150) ; 30 \%$ of $150=45$, or $(30 * 150) / 100$
so $150+45=195$
