Answer:
20% peanuts are there in the mixture of nuts.
Explanation:
Total weight of the mixture =25 lbs(10+15)
In the 25 lbs mixture of nuts, 68 % is peanuts, therefore finding the total weight of peanuts.
68 % of 25 lbs= 17 lbs.
There is a total 17 lbs of peanuts in the mixture .
15 lbs of peanuts was exclusively added, therefore the rest 2 lbs must have come from the mixture of nuts.
Therefore, there is a total of 2 lbs of peanuts in 10 lbs of mixture of nuts.
