    Efficiency is the ability to avoid wasting energy, materials, money, time, and effort in producing a desired result. We know the formula to find the answer AMA/IMAx100. Three supporting strings should have given M. A. of 3 provided that this is without friction. Since there are only 2, the efficiency is 2/3 = 66%.
