Question

A fruit-seller had some apples. He sells 40% of them and still has 420 apples. Find the
number of apples he had originally.
​

Answer 1

Answer:

Assume that the fruit seller had 100 apples initially.

He sell 40% of them =40 apples

Let out apples =(100−40)=60

In initial amount of apples if 60 of them are remaining =100

In initial amount of apples if 1 of them is remaining =(100/60)

In initial amount of apples if 420 of them are remaining =(100/60)×(420)

=(100×7)

=700

∴ the fruit seller had 700 apples.
