A man walks 1 km towards East and then he turns to South and walks 5 km. Again he turns to East and walks 2 km. After this he turns to North and walks 9 km. Now, how far is he from his starting point?
If 'P $ Q' means P is the father of Q; 'P # Q' means P is the mother of Q; 'P * Q' means P is the sister of Q, then how is B related to D in 'A $ B # C * D'?
