If 425 joules are absorbed from the higher temperature reservoir and 295 joules of that is passed onto the lower temperature reservoir, how much work has been done by the system?

425-295

sorry thats for chem..for physics 295-425

first you must define what is the system, if we consider the system to be both reservoirs, the the total energy of the system is increased by 425 J  and internal energy exchanges does not change the total energy of our system,

but: if we define the system to be the higher temp. reservoir then Abhishek1997's 2nd answer is correct!
