Question

Please solve step by step 

9.7. A Carnot engine is coupled to a Carnot refrigerator so that all of the work produced by the engine is used by the refrigerator in extraction of heat from a heat reservoir at 0°C at the rate of 35 kJ.s-1. The source of energy for the Carnot engine is a heat reservoir at 250°C. If both devices discard heat to the surroundings at 25°C, how much heat does the engine absorb from its heat-source reservoir? If the actual coefficient of performance of the refrigerator is @ = 0.6 @Carnot and if the thermal efficiency of the engine is n = 0.6 Carnot, how much heat does the engine absorb from its heat-source reservoir?
