I Only Need Two - Part II (Posted on 2006-01-23) Difficulty: 3 of 5
In I Only Need Two, you have 12 30g coins, 5 35g coins and a balance scale. As shown previously you can identify 2 of the 35g coins with 4 weighings. How many weighings are required if the scales can only weigh a maximum of 6 coins per side?
