Naman bought some apples for ₹720 from a shop. He negotiated the price and the shopkeeper reduced it by ₹2 per apple. Due to this, Naman could buy four more apples than he had bought earlier. How many apples did he originally buy?

1. 48
2. 44
3. 36
4. 40

Correct answer: 36

Solution

If the original number of apples is $x$, then original price per apple is $720/x$. After reduction, price per apple becomes $720/(x+4)$ and is ₹2 less. So $\frac{720}{x}-\frac{720}{x+4}=2$. Solving gives $x=36$.
