In an orchard, the ratio of the number of mango and
lichi trees is 3:4, respectively. Also, there are few apple trees in the orchard which is 30% more than the number of mango trees. Total number of trees in the orchard is 109. What is the number of lichi trees in the orchard? MTSolution
Let the number of mango trees and the lichi trees in the orchard be 3x and 4x respectively. According to the question, Number of apple trees in the orchard = 3x + 0.3 × 3x = 3.9x Therefore, 3x + 4x + 3.9x = 109 Or, 10.9x = 109 Or, x = 10 Number of lichi trees in the orchard = 4x = 40
