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? 

A) 3:2
B) 4:3
C) 2:3
D) 3:4

  A) 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 ✔
