A chemical engineer mixed 40ml of 80% HCl solution w/ 60ml of 12% HCL solution. He used a portion of the resulting mixtures & replace it with distilled water / H2O. If the new solution is 5.2% HCl, Howmuch of the original mixture did he used?

The new solution is 5.2% HCl before or after the distilled water was added? If it is after we need to know how much distilled water was used.
