Forty percent of the heat supplied is rejected by a reversible heat engine during a cycle of operation. What will be the COP if this engine is reversed and used as a heat pump?

The ratio between the high and the low working temperatures of a refrigerator based on reversed Carnot Cycle is 0.6. If a heat pump is operated between this same temperature range. what will be the COP of the heat pump?
