Total=30 Red=12 transparent=14 So 26 balls are accounted for. 5 red balls are made from glass. Glass balls which are not red=13-5=8 So out of 14 transparent balls , 4 must be glass. Maybe the remaining 4 are opaque. Yes . I think Jason81 is correct. Quote Link to comment Share on other sites More sharing options...

Not sure how you come to say 4 ... the total number of glass balls is 13, and 8 of which are not red -- all or some of them are transparent. I can't see your reasoning to reach @ 4.

0 Guest Posted March 28, 2008 Report Share Posted March 28, 2008 Reasoning for my answer of 4: Since the red balls' composition is given, we need to dismiss them. 30 - 12 = 18 So there are 18 balls left to find the configuration of. The number of glass balls left that are unaccounted for is 13 - 5 = 8 (5 of the glass balls we know are red). So there are 8 glass balls and 14 transparent balls. If we add 8 and 14 we get 22 balls, but we only need 18. So the difference is 4 balls (22 - 18). --Jason Quote Link to comment Share on other sites More sharing options...

I can't see your reasoning to reach @ 4. There are 30 balls totally. 12 are red. 14 are transparent and NOT red. So 26 out of 30 are accounted for. 13 glass balls are present. 5 are red , so they cannot be transparent. So 8 are remaining. Now already 26 balls are accounted for , but the glass balls present are 8. So out of 8 , 4 MUST be transparent.The other 4 as I mentioned before may be opaque or translucent. The above statement holds the key. Hope this makes it clearer. Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 28, 2008 Report Share Posted March 28, 2008 Hopefully this makes it even clearerThere are 4 Glass and Transparent balls With help from your diagram, I have to say that there are 8 transparent glass balls. The description sounds like glass balls are either red or transparent. Since only 5 are red, the rest (eight) are transparent. Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 28, 2008 Report Share Posted March 28, 2008 well 13 - 5 = 8 & 12 - 5 = 6 so there is 8 glass feft and there is 13 + 14 = 27 so there is 3 red balls mad from who knows what and there is 3 red balls left so there must be 3 transparent glass balls my answer is 3 Quote Link to comment Share on other sites More sharing options...

That may help. Or, look at it this way. Of 12 red balls, none are transparent; 5 are glass. Of 18 balls that are not red, there are the other 8 glass and all 14 transparent. Does that help?
