Correct answer: (C) 93.5%
Let marked price = p. SP of X = p×0.72×0.10 = 0.072p, and profit = 0.072p − 2000 = 322 ⇒ p = 32250. SP of Y at 88% discount = 32250×0.12 = 3870, profit = 1870, profit% = 1870/2000×100 = 93.5%.

सही उत्तर: (C) 93.5%
मान लीजिए अंकित मूल्य p है। X का विक्रय मूल्य = p×0.72×0.10 = 0.072p, तथा लाभ = 0.072p − 2000 = 322 ⇒ p = 32250। Y का 88% छूट पर विक्रय मूल्य = 32250×0.12 = 3870, लाभ% = 1870/2000×100 = 93.5%.
