Question

A price is increased by 15 to Rs. 230. What was the original price?

• A. 200
• B. 210
• C. 220
• D. 230

Hint:

For percentage increase, use $P \cdot (1 + \frac{r}{100}) = \text{new price}$ and solve for $P$.

Answer 1

The Correct Option is A

- Step 1: Set up. Let original price = $P$. $P \cdot 1.15 = 230$.
- Step 2: Solve. $P = \frac{230}{1.15} = \frac{230 \cdot 20}{23} = 200$.
- Step 3: Verify. $200 \cdot 1.15 = 230$.
- Step 4: Conclusion. Option (1) 200 is correct.
