lets consider total=100.so 88 students play games.in that 10 will play all.so students playing the games except the 10 students cricket will be played by 50,hockey 20,football 20.total=50+20+20=90.but it should be only 78(88-10).so students playing two games=90-78=12.students opted for only one game=78-12=66.

If there are 100 persons, only 88 participated.
with venn diagram of given data, we can find that
42 played only cricket.. 12 played only hockey...12 played only football.
4 played cricket & hockey...4 played football & hockey... 4 played cricket & football
10 played all three games.
so 42+12+12 =66 played only one game.
