Ahmed has 8 orange trees and four times as many apple trees in his orchard as Hassan. If Hassan has one apple tree and two orange trees, and they both have only apple and orange trees in their orchards, how many more trees are in Ahmed's orchard than in Hassan's? Let's answer step by step:
Ahmed has 4 times as many apple trees as Hassan who has 1 apple tree so Ahmed has 4 * 1 = 4 apple trees. Ahmed has 8 orange trees in addition to the apple trees for a total of 8 + 4 = 12 trees. Hassan has 1 + 2 = 3 trees in his orchard. Ahmed has 12 - 3 = 9 more trees than Hassan. The answer: 9.
