Solution:-

Assume that the fruit seller had 100 apples initially.

He sells 40% of them = 40 apples

Left out apples = (100 – 40) = 60

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

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

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

= (100 ×7)

= 700

∴the fruit seller originally had 700 apples.
