A shopkeeper has certain number of apples of which 10% are found to be rotten. He sells 85% of the remaining good apples and still has 405 good apples. How many apples did he originally have?
Answer & explanation
Correct answer: option 2
15% of Good apples = 405
Total number of Good people = \(\frac{20}{3}\) × 405 = 2700
Number of Good apples = 90% of Total number of apples
Total number of apples = \(\frac{10}{9}\) × 2700
= 3000
