1)1 can of concentrate is mixed with 3 cans of water into orange juice. 问How many 12-ounce cans of the concentrate are required to prepare 200 6-ounce servings of orange juice? 难道ounce这个单位有问题么 我死活弄不到答案上去。。。TT
2) If X and Y are integers greater than 1, is X a multiple of Y? I. 3y^2+7y=x II. x^2-x is a multiple of y. 答案说I alone sufficient 怎么算。。。。。
3)说共有132000要分到11个voting area, 且no area is to have a population 10% greater than population of any other area, 求 the minimum population of least populated area have? 选项有10700,10800,10900,11000(答案) 我用132000/11=12000 然后把选项一个一个带进去算,还是没有一个符合的。。。
Thanks ... |
