Daniel wins 25 percent of the first eight card games that he plays. If he loses all of the remaining card games that he plays, what was the total number of games that Daniel lost?

(1) Daniel played 20 card games.
(2) Daniel lost 90 percent of the card games that he played.



Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.



Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.



BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.



EACH statement ALONE is sufficient.



Statements (1) and (2) TOGETHER are NOT SUFFICIENT

IMO D

1) Suff. One can easily calculate the total no. of games lost which would be (.75)8 + (20-8)
2) Suff.
Let total no. of card games be x. Then (90x)/100 = 6 + (x-8) -- from this x & hence the no. of card games lost can be calculated
