Question
In an orchard, 70% of the trees are orange trees. The
number of guava trees is 30% of the orange trees, and the number of banana trees is 50% of the number of guava trees. If the number of banana trees is 105, find the total number of trees in the orchard.Solution
ATQ,
Let total number of trees in the orchard be 100x
Number of orange trees = 0.70 × 100x = 70x
Number of guava trees = 0.30 × 70x = 21x
Number of banana trees = 0.50 × 21x = 10.5x
So, 10.5x = 105
x = 10
Total number of trees in the orchard = 100x = 1000
