"Parida" and "Sarangi" are two coolies in a Railway Station. One day, they were given the responsibility to handle an important freight, to deliver it from Platform 2 to Platform 1. They were ordered to shift the freight in the least possible time.
Parida and Sarangi have to move 16 small boxes and 10 large boxes. The chart below indicates the time that each coolie takes to move each type of box:
