Question
In an orchard, the ratio of the number of mango and
lichi trees is 4:5, respectively. Also, there are few apple trees in the orchard which is 50% more than the number of mango trees. Total number of trees in the orchard is 90. What is the number of lichi trees in the orchard?Solution
Let the number of mango trees and the lichi trees in the orchard be 4x and 5x respectively. According to the question, Number of apple trees in the orchard = 4x + 0.5 × 4x = 6x Therefore, 4x + 5x + 6x = 90 Or, 15x = 90 Or, x = 6 Number of lichi trees in the orchard = 5x = 30
