Jack and Jill played a game for two people. In each game, the winner was awarded 2 points and the loser 1 point. No games were drawn. Jack won exactly 4 games and Jill had a final score of 10 points. How many games did they play?

Let's suppose that Jack won the first 4 games.....he would have 8 points and Jill would have - 4 points

 

So.....Jill would need to win the next  7 games to have a score of 10 points because  7(2) - 4  = 10

 

So.....they would have to play 11 games
