Hello dear readers, this weekend we have another challenge for you. This week Albert has to find out one contaminated vaccine sample from eight identical bottles. Now read the puzzle carefully and try to answer it.
Albert is very excited about the new job he got in a pharmacy lab. On his first day he received 8 bottles of sample vaccines. All bottles weigh same except for one.
Albert knows that one bottle is contaminated and needs to be eliminated before the testing. The bottles look identical and weight difference is so small it is impossible to identify that difference without using physical balance.
As he approaches towards the physical balance he finds out that he needs to pay $1 each time he uses the physical balance.
Can you guess what is the minimum amount Albert needs to spend to find out the contaminated bottle?
