Question:
A 4% peroxide solution is mixed with 10% peroxide solution,resulting in 100L of 8% solution.
To find amount of each Solution
Assume Volume of 2 peroxide solutions be x and y
When 100% peroxide solutions are mixed,it results in 100L solution
Hence, x+y = 100
When 4% solution and 10% solution is mixed ,it results in 100L of 8% solution
[tex] \frac{4x}{100} + \frac{10y}{100} = 8 \\ \\ 4x + 10y = 800 \\ \\ 2x + 5y = 400 \\ \\ [/tex]
[tex]x + y = 100 \\ \\ 2x + 2y = 200....(1) \\ \\ \ [/tex]
[tex]2x + 5y = 400....(2) \\ \\ (2) - (1) \\ [/tex]
[tex]3y = 200 \\ y = 66.66 \\ \\ x = 100 - 66.66 = 33.34[/tex]
Amount of each peroxide Solution
= 33.34L, 66.66L
