The Prevu Theater keeps a set of five counterweights to help stagehands move heavy props. The weights can balance exactly any load that is a multiple of 10 kg, from 10 kg up to a total of the five weights. Give the masses of weights which meet these conditions and allow the stagehands to counterbalance the maxium possible load.
