Correct answer: (D) 37.5%
Let marked price be m. SP of X = m×0.27×0.63 = 0.1701m, and profit = 0.1701m − 800 = 901, giving m ≈ 10000. SP of Y at 89% discount = 0.11×10000 = 1100, so profit% = (1100−800)/800×100 = 37.5%.

एक डीलर दो वस्तुएँ X और Y, ₹800 प्रति वस्तु की दर से खरीदता है। वह दोनों पर समान मूल्य अंकित करता है। वह X को 73% और 37% की दो क्रमिक छूट देकर बेचता है और फिर भी ₹901 का लाभ अर्जित करता है। यदि वह Y को 89% की एकल छूट पर बेचता है, तो Y पर लाभ प्रतिशत ज्ञात कीजिए।

सही उत्तर: (D) 37.5%
मान लीजिए अंकित मूल्य m है। X का विक्रय मूल्य = 0.1701m, और लाभ = 0.1701m − 800 = 901, जिससे m ≈ 10000। 89% छूट पर Y का विक्रय मूल्य = 1100, अतः लाभ% = (1100−800)/800×100 = 37.5%।
