Question

In a big garden 60% of the trees are coconut trees,25%of the number of coconut trees are mango trees and 20% of the number ofof mango trees are apple trees. if the number of apple trees are 1500 then the number of trees in the garden is?

Answer 1

the number of trees in the garden = x
coconut trees = 0.6x
mango trees = 0.6x * 0.25 = 0.15x
apple trees = 0.15x * 0.2 = 0.03x


0.03x = 1500
x = 1500/0.03
x = 50 000 ← the number of trees in the garden.
