Correct Answer: 9

Explanation:

Let, the number of wining game be 3x

The number of losing games be x

According to the question,

3x + 6 : x = 5

=> $\frac{3x+6}{x} = \frac{5}{1}$

=> 3x + 6 = 5x

=> 5x-3x = 6

=> 2x = 6

=> $x=\frac{6}{2}$

x = 3

The team won before It played the last six games = 3x = 3 x 3 = 9
