Let's assume L lit of first and M lit of second mixture is to be taken to prepare the third mixture.
In first mixture we have 24 lit of milk / 30 lit of mixture, hence fraction of milk in first mixture = 24/30
and fraction of water, 6/30.
Let's take a milk balance,
(fraction of milk in first mixture)(amount of first mixture) + (fraction of milk in second mixture)(amount of second mixture) = amount of milk in third mixure.
24L/30 + 15M/25 = 25
4L + 3M = 125 ..........(1)
Taking a water balance,
6L/30 + 10M/25 = 10
L + 2M = 50
or 4L + 8M = 200....(2)
Solving (1) and (2) we find,
L = 20 lit and M = 15 lit.
Hence 20 lit of first mixture and 15 lit of second mixture should be taken separately.
