Correct Answer - (4)
Solution:
Proportion of milk in 3 samples is 2/3, 3/5, 5/8.
Proportion of water in 3 samples is 1/3, 2/5, 3/8.
Since equal quantities are taken,
Total proportion of milk is 2/3 + 3/5 + 5/8 = 227/120
Total proportion of water is 1/3 + 2/5 + 3/8 = 133/120
Proportion of milk and water in the solution is  = 227:133
