One type of mixture contains 25% of milk another type of mixture contains 30% of milk. A container is filled with 6 parts of the first mixture and 4 parts of the second mixture. The percentage of milk in the mixture is .

(A) 27%
(B) 31%
(C) 29%
(D) 33%
(E) 30%

The mixtures are combined in a ratio of 6 to 4, so use a weighted average.

Total parts = 6 + 4 = 10

Milk percentage =
= (6 * 25 + 4 * 30)/10 =
= 27%

So the percentage of milk in the final mixture is 27%.

Answer: A.

You can solve it using alligation
6/4=30-x/ x-25 ....
