Question 1127570: A clothing manufacturer has some pure silk thread and some thread that is 85% silk. How many kilograms of each must be woven together to make kg of cloth that is 96 % of silk? Answer by greenestamps(13200) (Show Source):
In your post, you omitted the number of kg of cloth you want, so we can't give you the answer.
But we can tell you how to find the answer easily.
The 96% is 4% away from the 100% pure silk; it is 11% away from the 85% silk. That means the two kinds of silk must be mixed in the ratio 4:11; since 96% is closer to 100% than to 85%, the larger portion needs to be the pure silk.
ANSWER: mix the two kinds of silk in the ratio 11 parts pure silk to 4 parts 85% silk.
