A fruit seller had some mangoes. He sells 40% and still has 300 mangoes. How many did he originally have?

🧠 Explanation:

A fruit seller sold 40% of his mangoes and has 300 left, meaning 60% = 300. Thus, the original number is 300 ÷ 0.6 = 500. For math students, this highlights percentage calculations, making it a key topic for studying algebra and problem-solving.
