The ratio of milk and water in three containers of equal capacity is 2:1, 3:1 and 3:2 respectively. If all are mixed, find the ratio of milk and water in the mixture.
A121:59
B12:5
C7:3
D8:3
✓ Correct Answer: A — 121:59
Milk = (2/3 + 3/4 + 3/5) = (40+45+36)/60 = 121/60. Water = (1/3 + 1/4 + 2/5) = (20+15+24)/60 = 59/60. Ratio = 121:59.
