Show answer & explanation

Correct answer: A. 60% above the costलागत से 60% अधिक

Explanation

Let cost = 100, so required selling price = 120. After successive discounts, SP = M × 0.80 × 0.9375 = 0.75M. So 0.75M = 120 → M = 160, i.e. 60% above the cost.माना लागत = 100, तो आवश्यक विक्रय मूल्य = 120। क्रमिक छूटों के बाद विक्रय मूल्य = M × 0.80 × 0.9375 = 0.75M। अतः 0.75M = 120 → M = 160, अर्थात् लागत से 60% अधिक।
