Last Tuesday Ganesh went for the late night show and came late. In the morning family members asked him which movie did he see. He gave different answers to everyone. 1. He told to his father that he had gone to see MONEY. 2. According to his mom, he saw either JOHNY or BABLU. 3. His elder brother came to know that he saw BHABI. 4. To his sister, he told ROBOT. 5. And his grandpa heard that he saw BUNNY. Thus, Ganesh gave six movie names, all five letter words. But he saw some other movie with five letter word. Moreover, each of the six movie names mentioned above has exactly two letters common with the movie he saw. (with the same positions) Can you tell which movie did Ganesh saw?
