Answer
Correct Answer: ₹ 50
Explanation
Introduction / Context:Convert a gain percentage into a selling price using the multiplicative factor.
Given Data / Assumptions:
- CP = ₹ 40
- Gain% = 25%
Concept / Approach:SP = (1 + gain%) * CP.
Step-by-Step Solution:SP = 1.25 * 40 = 50
Verification / Alternative check:Gain = 10 on CP 40 ⇒ 25%.
Why Other Options Are Wrong:45, 48, 49, 55 are not equal to 1.25 * 40.
Common Pitfalls:Adding 25 to CP rather than 25% of CP, which coincidentally is correct here but fails in general.
Final Answer:₹ 50
