Ram hired a 3 wheeler from bus stand to his house. The driver A of 3 wheeler followed the shortest path and reached the destination in 1/2 an hour and charged Rs 50 from Ram. On the same day Ram's sister also came her house after attending a function in other city. She also came hired a 3 wheeler the diver B of 3 wheeler took an hour to reach and charged Rs 150 from her.
