Sets

65% of children in a sport club play football, 70% play volley-ball and 75% play basket ball. What is

the minimum number of children playing all the three games, if the total number of children in the

sport  club is 90

Re: Sets

hi juan

Welcome to the forum.

Have a look at this thread:

I have shown there how you can do these 3 set problems.

ps.  I'm a bit worried about these children as there seem to be half children in some sets.
