      Question

      160 ml of mixture A containing milk and water in the

      ratio of 3:2 respectively is mixed with another 160 ml of mixture B containing milk and water in the ratio of 1:4 respectively. Find the ratio of milk to water in the resultant mixture.
      A 1:2 Correct Answer Incorrect Answer
      B 2:3 Correct Answer Incorrect Answer
      C 3:4 Correct Answer Incorrect Answer
      D 4:5 Correct Answer Incorrect Answer
      E 5:6 Correct Answer Incorrect Answer

      Solution

      Quantity of milk in 160 ml of mixture A = 3/5 Γ— 160 = 96 ml
      Quantity of water in 160 ml of mixture A = 2/5 Γ— 160 = 64 ml
      Quantity of milk in 160 ml of mixture B = 1/5 Γ— 160 = 32 ml
      Quantity of water in 160 ml of mixture B = 4/5 Γ— 160 = 128 ml
      Desired Ratio = (96 + 32):(64 + 128) = 128:192 = 2:3
