Seventy percent of the 30,000 trees in an orchard are apple trees, and the rest are pear trees. What percent of the trees in the orchard were planted this year?

From the question itself, you can calculate the number of apple trees and the number of pear trees . Statement 1alone tells you nothing, since you don't know how many apple or pear trees were planted this year, so you should write down BCE. Statement 2 gives you enough information to calculate the number of pear trees planted this year (you can make a ratio box, or just calculate ), but no information about the apple trees, so you should eliminate B. If you look at the two statements together, you know that 1,000 pear trees were planted this year, and apple trees were planted prior to this year, so apple trees were planted this year. So, of the trees were planted this year. Don't bother to turn this number into a percent: since you know you could. The answer is C
