@Sohini: If you dont know the concept of Maximum Power Transfer Theorem, then simply find the expression for power and apply MaximaMinima. You will get this.

This is simple maximum power transfer theorem which says if internal resistance is equal to load resistance then the power transformed will be max.so the answer will be R=0.5
