Question

I played 4 games of badminton and scored an average of 12 points per game. The average score of the first 3 games was 10 points per game. How many points did I score in the 4th game?

Answer 1

Answer:

18

Step-by-step explanation:

average score in each game=12

total score in 4 games=score in each game x total number of games played

                                    = 12 x 4=48

average score of first three games=10 points each

score in fourth game

=total score - (3 x average score of each of the first 3 games)

=48 - (3 x 10)=48-30=18
