Question

A person bought an item for Rs. 1350 and spent Rs. 150 towards transportation of the item. Then he sold it for Rs. 1800. The profit percentage is:

• A. 25%
• B. 15%
• C. 20%
• D. 10%

Hint:

Always calculate your profit percentage based on the final total cost price, not the initial purchase price. $$\text{Ratio of Cost to Profit} = 1500 : 300 \Rightarrow 5 : 1$$ Since $\frac{1}{5}$ corresponds to exactly $20\%$, you can identify the correct answer choice without tedious scratch calculations.

Answer 1

The Correct Option is C

Step 1: Total CP.
$1350+150=1500$.
Step 2: Profit %.
$(1800-1500)/1500\times100$ \[ \boxed{20\%} \]
