Profit and Loss – Simple loss percent on a small transaction: A person buys a watch for ₹ 500 and sells it for ₹ 300. What is the loss percentage?

Difficulty: Easy

Correct Answer: 40%

Explanation:

Introduction / Context:
This is a straightforward loss percentage computation using CP and SP.

Given Data / Assumptions:

CP = ₹ 500
SP = ₹ 300

Concept / Approach:
Loss% = (CP - SP) / CP * 100.

Step-by-Step Solution:
Loss = 500 - 300 = 200Loss% = 200 / 500 * 100 = 40%

Verification / Alternative check:
40% of 500 is 200; subtracting yields SP 300, consistent.

Why Other Options Are Wrong:
30%, 35%, 45%, and 50% do not equal 200 / 500 * 100.

Common Pitfalls:
Using SP as the denominator.

Final Answer:
40%
