Legend has it that the Indian mathematician Khawarizmi (a1-khawarizmi, AD 780-850) wrote a will when his wife was pregnant with the first child, which read: If my dear wife helps me to have a son, my son will inherit two-thirds of the estate, and my wife will receive one-third; if a daughter is born, my wife will inherit two-thirds of the estate, and my daughter will receive one-third. Unfortunately, before the child was born, Khwarizmi passed away, leaving behind a legacy of 168 taels of gold. But God made fun of people, his wife gave birth to a pair of twins, a boy and a girl. You are smart, please help them distribute this inheritance fairly in a way that conforms to Khwarizmi's last wish! May I ask how much gold can my son get?
传说印度数学家花拉子密(a1-khawarizmi，公元780一850)在他太太怀第一胎时，写了一份遗嘱，内容为：如果我亲爱的妻子帮我生个儿子，我的儿子将继承三分之二的遗产，我的妻子将得三分之一；如果生女儿，我的妻子将继承三分之二的遗产，我的女儿将得三分之一．不幸地，在小孩出生前，花拉子密就去世了，遗下了168两黄金的遗产．而老天作弄人，他的妻子竟然生下一对双胞胎，一男一女．聪明的你，请帮他们依照符合花拉子密的遗愿的方式公平地分配这笔遗产吧!请问儿子可分得多少两黄金？
