Show answer and explanation
Correct answer: (A) 22.5%
SP of X = M×0.2×0.56 = 0.112M; since profit=172, SP_X=1372, so M=₹12,250. SP of Y at 88% discount = 0.12×12250=₹1,470; profit=270, so profit% on Y = 270/1200×100 = 22.5%.

सही उत्तर: (A) 22.5%
X का SP = M×0.2×0.56 = 0.112M; लाभ=172 होने से, SP_X=1372, अतः M=₹12,250। Y पर 88% छूट पर SP = 0.12×12250=₹1,470; लाभ=270, अतः Y पर लाभ% = 270/1200×100 = 22.5%।
