Good luck from Lisa in SH作者: zyh79 时间: 2002-11-12 13:18
suppose such a situation: 100 employees among which 90 belong to low-paying service and 10 high-paying service. The rate of increase in both low-paying and high-paying service is 10%, then low-paying increases 9 and high-paying increase 1. Be careful the unchanged shares. The share of low-paying is 90% and that of high-paying is 10%. If the increase in low-paying is a little more than 9, say 10. then the share of it will no doubt increase. At the same time the overal increase of employment is more than 10%. Now come the same situation as described above.作者: lisaislisa 时间: 2002-11-12 16:28
