How to solve the earthwork combined output of these 3 equipment in cubic meter per hour?

Question

If one excavator can excavate 40 m3/hr, one loader can load 50 m3/hr and one dump truck can haul & dump 60 m3/hr?

Answer 1

Take LCM of 40,50,60

10)4,5,6

   2)2,5,3

LCM-600

600/40=15 Excavators

600/50 = 12 Loaders

600/60 =10 Dump trucks

( Employ these equipment in the ratio 15:12:10 )

Answer 2

40 cubic meters per hour only. Even the loader and the dump truck can potentially carry and work more, they're still dependent on the output of the excavator.
