紧急求助：请教一道九月份KFC 九月份KFC的第二题

flutemama

PS:A shop sells t-shirt in white and red with two sizes: medium and large...the store sell twice as median red T-shirt as many as large red T-shirt ...How many medium t-shirt does the shop sell?

T-SHIRT卖了中号和大号的红和白两种T-SHIRT,卖的中号红是卖的大号白的N倍，卖的中号白石卖的大号红的M倍，然后说红的总共卖了90，白的卖了190，最后问中号的总共卖了多少， 这里在M和N是已知的还是未知的？如果是未知的，在未知的情况下如何计算出结果呢？ 如果是已知  sell twice as median red T-shirt as many as large red T-shirt 是说 红色中号Tshirt是 红色大号的两倍还是反过来的意思呢？
