Contaminated pill!
June 15, 2007You have ten jars of pills.One jar of pills is contaminated.The
only way to tell which pills are contaminated is by weight.A
regular pill weighs 10 grams; a contaminated pill weighs 1.1 grams.
You are given a scale and allowed to make just one measurement
with it.How do you tell which jar is contaminated?
Solution:
1- Take 1 pill from 1st jar,2 pills from 2nd jar and so on. .. …
n pills from nth jar.
