Question

A crate of mangoes contains one bruised mango for every thirty mango in the crate. If three out of every four bruised mango are considerably unsaleble and there are 12 unsaleable mangoes in the crate then how many mango are there in the crate?

Answer 1

Let the total no of mangoes in the crate be x

Then the no of bruised mango = 1/30 x

Let the no of unsalable mangoes =3/4 (1/30 x)

1/40 x =12

x = 480
