As you found, 31 play Football and Tennis. But there is no way to know how many play exactly which one sport. Clearly, n can be any multiple of 3.
For example, if n=3, then there are 6 people who play exactly one sport, but there's no way to know how those six are designated.
There must be some other piece of information relating the relative numbers for the one-sport players.
The 79 members of a spot club play at least one of the following games Tennis, Football and Volleyball. 19 play Football & Volleyball and 29 play Tennis & Volleyball, n play all the three games. 2n people , each play only one game. How many play Volleyball altogether.?
