who can explain the No 8 for me ? 8. PS:公司的部门员工占全部人数的22%,为了扩大部门,add 2 employees new to the company for current employee in the department. 问增加人数后比例变为多少。 多谢FIGHTING618指正~ 每个现有的employee加上2个新employee,则增加22*2=44个。 (44+22)/(100+44)=66/144=45.88% what does the 则增加22*2=44个 mean? why * but not +? -- by 会员 killerinJP (2011/6/23 6:34:57)
My best guess is that the original wording of the problem goes something like this: Certain department makes up for 22% of the company. If the company were to add 2 new employees for every current employees, what percentage of the company will this department take up.
as for you other question: it's (27 times cube root of 3) divid by (9 times square root of 2)
Was that clear? |
