A solution containing 35% of milk is mixed with another mixture containing m% of milk in equal proportions. The mixture so formed contains 50% of milk. What is the value of m?
Show answer & explanation
Correct answer: C
Explanation
Given:
Milk in the first solution = 35%
Milk in the second solution = m%
Both are mixed in equal proportions
Milk in the new mixture = 50%
By the formula:
Average percentage when mixed in equal proportions = (First percent + Second percent) / 2
(35 + m) / 2 = 50
35 + m = 100
m = 100 − 35
m = 65%
