Let x be the amount of bleach powder used in the mixture.
According to the given ratio, the amount of peroxide used is 3 times the amount of bleach powder used.
So, the amount of peroxide used = 3x
The total amount of the mixture is 175 ml.
Therefore, x + 3x = 175
4x = 175
x = 175/4
x = 43.75 ml
So, the amount of peroxide used = 3x = 3 * 43.75 = 131.25 ml
Therefore, the amount of peroxide used in the mixture is 131.25 ml.
