9. Cost Price from Loss on Selling Price

Type 1:
Example 9: A shopkeeper sells a product at ₹680 and incurs a loss of $15\%$. Find the cost price.
Solution:

$$SP = CP \times (1 - \text{Loss\%})$$ $$680 = CP \times (1 - \frac{15}{100}) \implies 680 = CP \times 0.85$$ $$CP = \frac{680}{0.85} = 800$$

Answer: ₹800
