      C 123 Correct Answer Incorrect Answer
      D 170 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ, After removal of 100 litres of mixture, Let the initial quantity of water be '100f' litres. Initial quantity of alcohol = 0.5 Γ— 100f = '50f' litres. ATQ, 100f - 50f = 40 Or, 50f = 40 Or, 'f' = 40/50 = 0.8 Therefore, final quantity of water = 100f + 50 = 100 Γ— 0.8 + 50 = 80 + 50 = 130 litres
