  • Question
  • The concentration of glucose in three different mixtures (glucose and alcohol) is 12,35 and 45 respectively. If 2 litres, 3 litres and 1 litre are taken from these three different vessels and mixed. What is the ratio of glucose and alcohol in the new mixture?


  • Options
  • A. 3:2
  • B. 4:3
  • C. 2:3
  • D. 3:4

  • Correct Answer
  • 3:2 

    Explanation

    Concentration of glucose are in the ratio = 1 2 : 3 5 : 4 5

    Quantity of glucose taken from A = 1 liter out of 2

    Quantity of glucose taken from B = 3/5 x 3 = 1.5 lit

    Quantity of glucose taken from C = 0.8 lit

    So, total quantity of glucose taken from A,B and C = 3.6 lit

    So, quantity of alcohol = (2 + 3 + 1) - 3.6 = 2.4 lit

    Ratio of glucose to alcohol = 3.6/2.4 = 3:2
