GMAT OFFICIAL GUIDE PS

Solution:

We are given that Rose exchanged $500.00 for euros at an exchange rate of 0.80 euro per dollar. Since 1 dollar = 0.8 euros, 500 dollars = 500 x 0.8 = 400 euros.

Since she spent spent 3/4 of her euros, she was left with 1/4 x 400 = 100 euros.

Finally, she exchanged her remaining euros for dollars at a rate of 1.20 dollars per euro.

Since 1 euro = 1.20 dollars, she ended up with 100 x 1.2 = 120 dollars.

Answer: D
