Three glasses of sizes containing 3 litres, 4 litres and 5 litres contain mixture of milk and water in the ratio 2: 3, 3: 7 and 4: 11, respectively. The contents of all the three glasses are poured into a single vessel. So, the ratio of milk is:

2:3 , 3:7 , 4:11

Milk = \frac{2}{5} + \frac{3}{10} + \frac{4}{15}

\frac{\left ( 12+9+8 \right )}{30}= \frac{29}{30}

Water = 3/5 + 7/10 + 11/15

(9+21+22)/30 = 52/30

M:W = 29:52
