The HCL acid and water in two vessel A and B are in the ratio of 4:3 and 2:3 respectively.
in what ratio the liquids in both the vessel be mixed to obtain a new mixture in vessel C containing half HCL and Half water?

[Rutherford]

Mark the volume of both liquids with two unknowns, express the volumes of HCl and water in both liquids through these unknowns and make an equation from the data that the new liquid contains half water and half HCl. Then calculate the ratio of the unknowns.
