Calculation of working hours [closed]

When I was hired at Company $A$, I agreed I would work for them three days a week and be sent to work at Company $B$ for the other two working days. Company $A$ would then contribute to my wage for $\frac{3}{5}$, while Company $B$ would account for the remaining $\frac{2}{5}$.

A few months passed and, since life has its bumps, I couldn't precisely follow that plan (due to illnesses and vacations). As of today, I worked $247$ hours at Company $A$ and $184$ hours at Company $B$.

Company $A$ claims this situation is not right and that it must be corrected by making me work for them exclusively, before I can go back to Company $B$. How many extra hours will I have to work at Company $A$ before they're happy, so I can be sent to work at Company $B$ again?

I've made my calculation but I find myself in need of peer review. I hope you'd help me, thanks in advance!

It's ok, I deliberately left off my calculation as I deemed it not necessary. @deepakm was able to provide the answer I was looking for, as it matched my own calculation. –  user3145982 Jan 29 at 14:29
