Over the last two years, who made more money investing in the stock market, Leslie or Kerri?

(1) Leslie made an average rate of return (arithmetic mean) of 20%, and Kerri made an average rate of return (arithmetic mean) of 5%.
(2) Kerri started with two times as much money as Leslie.
Ignore this problem.
The GMAT would not expect a test-taker to know the term average rate of return.
