How Would You Move Mount Fuji?

Recently my bedtime storybook has been "How Would You Move Mount Fuji?" a collection of puzzles and questions posed by smart companies such as Microsoft during their interviews to select the most creative thinkers. It's a wonderful read and I'm so amazed by the ingenious solutions to the equally ingenious questions... gets me v high... LOL

here's one that i can't forget... chris also thinks it's super cool...

Q: You have 5 jars of pills. All the pills in one jar are "contaminated". The only way to tell which pills are contaminated is by weight. A regular pill weighs 10g; a contaminated pill is 9g. You're given a scale (that tells exact weight in g) and allowed to make just ONE measurement with it. How do you tell which jar is contaminated.

A: tell u tomorrow. the answer is so simple yet so cool.

another weight-related question is the famous: You have 8 balls. one of them is defective (i.e. weighs more than the others). how do u tell, using a balance (the type the woman at supreme court carries), which ball is defective in two weighings?

answer tomorrow ya...
