Difficulty: Easy
Correct Answer: ₹ 276
Explanation:
Introduction / Context:
“Gain equal to 1/6 of outlay” means the profit is 1/6 of cost price (CP). Therefore, selling price (SP) equals CP plus CP/6 = (7/6)CP. We invert this to find CP from the given SP.
Given Data / Assumptions:
Concept / Approach:
Rearrange CP = SP * (6/7). This is a simple proportional relation.
Step-by-Step Solution:
CP = 322 * (6/7) = 1932 / 7 = ₹276
Verification / Alternative check:
Check: Profit = 322 − 276 = ₹46, which is 1/6 of 276 (since 276/6 = 46). Correct.
Why Other Options Are Wrong:
₹300/₹376/₹175 do not satisfy SP = (7/6)CP with SP = ₹322.
Common Pitfalls:
Using 1/6 of SP instead of CP; mishandling the fraction inversion when solving for CP.
Final Answer:
₹ 276
