Efficiency of carnot heat engine,if source temperature is T1K and sink temperature is T2K

The efficiency of a Carnot's engine at a particular source and sink temperature is (1)/(2) .When the sink temperature is reduced by 100^(@)C , the engine efficiency, becomes (2)/(3) . Find the source temperature.

The efficiency of carnot engine is 50% and temperature of sink is 500K. If temperature of source is kept constant and its efficiency raised to 60%, then the required temperature of the sink will be : -
