You can put this solution on YOUR website!
We would not know because the concentration of each of the three liquids is not given.

6% of 125 ml is 7.5 ml.
4% of 225 ml. is 9 ml.
9% of 259 ml. is 23.31 ml.

This only means that when you mix all three, you have 7.5%2B9%2B23.31=highlight%2839.81%29 ml. of mixtures combined.
