    A 82 Correct Answer Incorrect Answer
    B 83 Correct Answer Incorrect Answer
    C 84 Correct Answer Incorrect Answer
    D 85 Correct Answer Incorrect Answer

    Solution

    Let water = a, milk = 1.1a
    ⇒ 2.1a = 210 ⇒ a = 100, Milk = 110
    Now, (110 + n + 4):(100 + n - 4) = 11:10
    ⇒ (114 + n):(96 + n) = 11:10
    ⇒ 10(114 + n) = 11(96 + n)
    ⇒ 1140 + 10n = 1056 + 11n
    ⇒ n = 84
