                A football team won 10 matches out of the total number of matches they played. If their win percentage was 40, then how many matches did they play in all?

Answer:

                \[\because \] If 40 matches were won, then the total number of matches played = 100 \[\therefore \] If 1 match was won, then the total number of matches played \[=\frac{100}{40}\] \[\therefore \] If 10 matches were won, then the total number of matches played \[=\frac{100}{40}\times 10=25\] Hence, they played 25 matches in all.
