(1) Daniel played 20 card games.
(2) Daniel lost 90 percent of the card games that he played.
He does not win any games after the first 8.
Thus, the total number of games won = .25(8) = 2.
Statement 1: Daniel played 20 card games.
Total number of games lost = 20-2 = 18.
SUFFICIENT.
Statement 2: Daniel lost 90 percent of the card games that he played.
Thus, he won 10% of the games.
Since he won a total of 2 games, and 2 is 10% of 20, the total number of games played = 20.
Total lost = 20-2 = 18.
SUFFICIENT.
The correct answer is D.
