Question

Juan and Mary play a two-person game in which the winner
gains 2 points and the loser loses 1 point. If Juan won exactly
3 games and Mary had a final score of 5 points, how many
games did they play?

Answer 1

Answer:

4

Explanation:

Answer 2

Answer:

Answer is 7

Explanation:

If Juan won 3 games which means 6 points and Mary lost those 3 games which means -3. After that Juan didn't won any game which means that Mary won the other games. If Mary won 1 game, then her points will become -3 + 2 = -1, and if 2 games, then it will become -1 + 2 = 1, and if 3 games, then it will become 1 + 2 = 3 and if 4 games, then the points will become 3 + 2 = 5.

So no. of games = No. of games won by Juan + No. of games won by Mary= 3 + 4 = 7 games

And the Question only asked games and in which Mary should have 5 points. It didn't asked Juan's points so the answers are given correct with the correct condition.
