Question 1187626: A goldsmith needs 150 grams of Gold alloys of 80% pure gold. Only two alloys of gold are available, the first being 90% pure gold and the other is 70% pure gold. How many grams of 85% pure gold must be used to suit the requirement? Found 2 solutions by josgarithmetic, ikleyn:Answer by josgarithmetic(39617) (Show Source):
If the two AVAILABLE alloys are 90% Gold and 70% Gold, and the goldsmith wants 150 grams of 80% alloy then this is exactly in the middle of the two alloys available.
75 grams of each available alloy will give him the desired 80% alloy.
