    A 25 Correct Answer Incorrect Answer
    B 18 Correct Answer Incorrect Answer
    C 40 Correct Answer Incorrect Answer
    D 46 Correct Answer Incorrect Answer

    Solution

    ATQ, we can say that. Let the initial quantity of orange juice = 3x and the initial quantity of Apple = x ATQ, (x + 10)/3x = 5/3 3x + 30 = 15x (equation 1) Also (x + 20)/3x = 7/4 4x + 80 = 21x (equation 2) Solving equation 1 and 2, we get x =40 Initial quantity of orange juice = x = 40 = 40 liters
