376.Three people at work. The salary are X, 2X per hour, and 3x, respectively, for the level1 and level2 and level3. Q is how many more minutes the level1 has to work in order to get 1 dollar level3 work if both level1 and level3 work in one hour(not sure how the sentence made)? 1) Level 1 is 10.5$ per hour 2) Level2 to level3 is ?? ” 题目是问的LV1赚一块钱比LV3要多花多少时间。 条件一:知道LV1一小时赚多少可以得出每分钟的,题中也给出了3者之间的SALARY比例。即可得出所求。 条件2,:LV2与LV3的比?不清楚是什么比。 375.一个数列第一项是1,然后后面各项可以是前一项的两倍或者三倍, 我做的问的是:a2-3a3+a4 (提供者IDyzcww ) 这题好像前面有过,应该是问MAX和MIN。 MAX:3 MIN: -12 374.三七四 一分钟fill out600个罐头,B一分钟800个,C一分钟put lid on2400个罐头.A bottle which is filled out will be lid, a bottle which is not filled out will not be lid. Q: how many machines are there working in one minute? (1) There are 4800 cans filled out in a minute(和之前的机经不同,之前是4800 lid) (2) For every C machine, there will be 2 B machine. (提供者ID:whataboutnow) 查了下和原来的32有些区别,数字也有变化。 条件一:不论是CANS还是LIDS,都无法确定。 条件二:如果C被定为要配2台B的话,那意味着2400里的1600是产于B的。 剩下了800. 这其中A不可能参合进来了。所以还是B去完成。所以条件2是可以解答的。 -- by 会员 AmoHolmes (2012/4/22 6:22:01)
