RE: QUIZ Test #17- can you solve this? difficulty level: HARD
I got it! And in only two measures =)
- Split the balls into three groups of four
- Measure groups 1 and 2
- Then measure the heavier group of above(lets call it group 1) and group 3.
- If group 1 balances with group 3, then group two has a lighter weight ball.
- If group 1 is heavier then group 3, then group 1 has a heavier weight ball.
how'd I do???
