    Solution

    ATQ, Let the cost price of 1 ml Lemon soda be Rs. ‘m’. So, the cost price of 1 ml juice = Rs. 1.5m Cost price of the whole content juice seller had = 120 × 1.5m + (30 + 30) × m = Rs. 240m Total quantity of mixture sold = 120 + 30 – 50 + 30 = 130ml Selling price of 1 ml mixture = 1.6 × 1.5m = Rs. 2.4m So, the selling price of the whole mixture sold by him = 130 × 2.4m = Rs. 312m So, the profit percent = {(312m – 240m)/240m} × 100 = 30%
