QUESTION: 113

John must arrange 3 different physics books and 3 different mathematics books on one shelf. If the first book on the leftmost side is a mathematics book and no physics book is next to another physics book. How many different arrangements exist?

6
9

QUESTION: 114

An investor receives a total combined return of 7% on his two different investments. On his $10,000 investment he receives a return of 6%. What is the return on his $20,000 investment?

7.25%
7.5%
8%
8.5%
9%

Answer(s): B

Explanation:

The combined return is 7% of $30,000 = $2,100. Subtract the 6% return on his $10,000 investment = $600. $2,100-$600=$1,500. This is the return on his second investment of $20,000. $1,500 of $20,000 is a 7.5% return.
