Brain Teasers
Drash and Rabb
On the Planet Necro there are two types of metals. One is Drash which weighs 127 Necrograms, and Rabb which weighs 50 Necrograms. You have as much play-doh, Drash, and Rabb as you need. You have a balance scale and you need to make a ball of play-doh equal to 304 Necrograms. How?
Answer
Put the Rabb on the scales. Put play-doh on the opposite side so it balances the Rabb. Then divide the play-doh in half so that each half balances the other. Now you have a 25 Necrogram ball of play-doh. Now put the Drash on the scales and enough play-doh to balance it, then mix the 127 and 25 Necrogram balls of play-doh together. That makes 152 Necrograms. Put that ball on the scales and enough play-doh to balance that. Combine these and you will have a 304 Necrogram ball of play-doh.Hide Answer Show Answer
