Correct answer: (A) 42.5%
Let marked price be m. SP of X after successive discounts of 60% and 20% = 0.4×0.8×m = 0.32m, and profit = 0.32m − 700 = 630, giving m = 1330/0.32 = 4156.25. SP of Y at 76% discount = 0.24m = 997.5, so profit on Y = 997.5 − 700 = 297.5, which is 297.5/700 × 100 = 42.5%.

सही उत्तर: (A) 42.5%
मान लीजिए अंकित मूल्य m है। 60% और 20% की क्रमिक छूट के बाद X का विक्रय मूल्य = 0.32m, और लाभ = 0.32m − 700 = 630, जिससे m = 4156.25। 76% छूट पर Y का विक्रय मूल्य = 0.24m = 997.5, अतः Y पर लाभ प्रतिशत = 297.5/700 × 100 = 42.5%।
