Hi, I'm in desperate need for help. Any guidance in the right direction will be appreciated:

Heat Q flows spontaneously from a reservoir at 394 K into a reservoir that has a lower temperature T. Because of the spontaneous flow, thirty percent of Q is rendered unavailable for work when a Carnot engine operates between the rservoir at temperature T and a reservoir at 248 K. Find the temperature T.

2. Relevant equations

W=TS

3. The attempt at a solution

0.30Q = TS, where S = Q*/T

I know the T is in between and the Q value from the drop of 348 to T, multiplied by 0.30 will give you the work needed. I'm just so confused; any help will be appreciated! Thanks!
