Two vessels having volumes in the ratio 3:5 are filled with water and milk solutions. The ratio of milk and water in the two vessels are 1:2 and 3:2 respectively. If the contents of both the vessel are empties into a larger vessel, find the ratio of milk and water in the larger vessel.  Choose the correct answer
A) 99 : 61
B) 1 : 1
C) 61 : 160
D) 61 : 99
E) 99 : 160

Rationale: vessel a = 300 gallons - - > milk = 100 , water = 200 ; vessel b = 500 gallons - - > milk = 300 , water = 200 ; vessel a + b = 800 gallons - - > milk = 400 , water 400 . the ratio = 400 / 400 - - > 1 : 1 answer : b
Answer: B
