A certain grain depot transported 2000 bags of the total stock (1/3) in the morning, and another 6000 bags in the afternoon. At this time, the grain in the grain depot was less than the original (1/6). May I ask: How many bags of grain are there in stock? ?
某粮库上午运走全部存量的(1/3)又2000袋，下午又运进6000袋，这时粮库中的粮食比原来少了(1/6)，请问：原来粮库存粮多少袋？
