    Solution

    ATQ, Quantity of bottle Q = q Quantity of bottle P = 50 - q CP of the mixture = q × 48 + (50 - q) × 68 = 3400 - 20q SP of the mixture = 50 × 68 = 3400 Profit = (3400 - (3400 - 20q))/(3400 - 20q) × 100 = 12 1600q = 38080 - 160q q = 20 CP of the mixture = 3400 - 20 × 20 = 3000 New SP of the mixture = 50 × 48 = 2400 Required loss percentage = (3000 - 2400)/3000 × 100 = 20% loss
