The number of female workers in a certain factory accounts for (3/4) of the total number of workers in the whole factory. If the number of male and female workers increases by 60 each, then female workers only account for (2/3) of the total number of workers in the factory. How many people are there in the whole factory?
某厂女工人数占全厂人数的(3/4)，若男、女工人各增加60人，女工这时只占全厂人数的(2/3)，求原来全厂共有多少人？
