In a group, 20 children like milk, 26 like fruit, 10 like toast, 8 like both milk and fruit, 4 like toast and fruit, 2 like toast and milk and 2 like all the 3 items, how many children are there in the group?
Not sure but it should be 26 because all the pairs can come out from it like 8 like both milk and fruit so these children can be from these 26 children.

wondering just what is the criteria for registering on this forum and gaining a reputation when some of the posters have a reputation of 10...is it 10 from the bottom or 10 from the top?
