word problem
On the shelf you have 10 idential bottles of identiacal pills(100 in eachbottle) However one of those 10 bottles contains cheap knockoff pills the only way to differentiate fake pills from real pills is the weight while real pills weigh 1 g each, the knockoff pills are only .9 g. You have one scale that shows the exact weight(down to the mg) of whatever is weighted.

How can you tell which bottle contains fake pills with just a weighing?
