In the first M games of a team's season, the ratio of the team's wins to its losses was 1:2. In the subsequent N games, the ratio of the team´s wins to losses was 2:3. If M:N = 4:5, what was the ratio of the team's wins to its losses for all M+N games? Choose the correct choice from the following answers.
A) 7:18	B) 9:23	C) 10:17	D) 23:54	E) 31:77
M = 4/9 of total games   N = 5/9 of total games   Wins = 1/3*4/9 + 2/5*5/9 = 4/27 + 6/27 = 10/27   Losses = 1 - 10/27 = 17/27   The ratio of wins to losses is 10:17.   The answer is 10:17.
