Because of the buoyancy, the weight of gold is reduced by (1/19) when weighed in water; the weight of silver is reduced by (1/10) when weighed in water. A gold-silver alloy weighing 500 grams is weighed in water, and its weight is reduced by 32 grams. How many grams of gold is contained in this alloy?
由于浮力作用，金放在水中称量，其重量减轻了(1/19)；银放在水中称量，其重量减轻了(1/10)．有一重500克的金银合金，放在水中称量，其重量减轻了32克，这块合金中含金多少克？
