Cycle time of power shovel of 2 m$^{3}$ capacity is 30 seconds. Truck of 8 m$^{3}$ and 12 m$^{3}$ are available at the rate of Rs.800 and Rs.1200/day respectively for 10hrs. The cycle time of 8 m$^{3}$ truck is 14 minutes and 12 m$^{3}$ tucks are 16 minutes. How do you balance the operation of shovel and truck with least idle time and minimum cost.

Balancing of equipment is a process in which the equipments used for construction are not allowed to remain idle for a long duration of time.Remaining idle may further increase its maintenance cost and it also reduces efficiency of work by considerable amount.
