Ok I got it ... thanx 'jason' and 'grey cells' for the explanation.Into one box there are 30 balls:12 of them are red,13 balls are made from glass and 14 are transperant.If the red balls are not transperant,but 5 of them are made from glass,then how much from the glass balls are transperant?

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

my answer is 3

Check your math in red above. 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?
