A fruit-seller had some apples. He sells 40% of them and still has 420

1.	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» Assume that the fruit seller had 100 apples initially. He sell 40% of them = 40 apples Left 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 originally had 700 apples.

Answer»

Assume that the fruit seller had 100 apples initially.

He sell 40% of them = 40 apples

Left 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 originally had 700 apples.
