我認為題目這邊1997可能打錯了!!猜想應該為1977...

所以本題GWD題目有誤囉!!
那如果改成1977則計算如下

先設1977有X個女員工
1987則有1.6X個女員工

A選項
1977 到1997增加了200%
則表示1977的女員工數量=150
1987則有150*1.6=240
1987~1997增加的比例為300/240=1.25....increase 25%

B選項
1977有100個女員工
則1987有160個女員工
1987~1997增加的比例為300/160=1.875....increase 87.5%

Therefore the answer is D
If there is any mistake, kindly give your input!

請問一下？
如果修正題目後∼
increase 200% 不是應該增加2倍嗎？，
所以要以三倍來計算，那麼1977的人數應為100人！

是不是阿？
有人可以幫我確認一下嗎？

是滴
你的觀念是對的
(A)中的increased by 200%，指的就是1997人數=1977人數 x 3
