In a corporation, 50 percent of the male employees and 40 percent of employees are at least 35 years old. If 42 percent of all the employees are at least 35 years old, what fraction of the employees in the corporation are female? 這題我想了好久可是還是沒算出來>< 有人下可以幫我ㄧ下嗎 感激 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.217.145.25
