Seed mixture X is 40% ryegrass and 60% bluegrass by weight; seed mixture Y is 25% ryegrass and 75% fescue. If a mixture of X and Y contains 34% ryegrass, what percent of the weight of the mixture is from mixture X? Choose the correct choice from the following options
A) 25%	B) 40%	C) 50%	D) 60%	E) 75%
34% is 9%-points above 25% and 6%-points below 40%.   Thus the ratio of mixture Y to mixture X is 2:3.   The percent of mixture X is 3/5 = 60%.   The answer is 60%.
