In 1997 there were 300 femal employees at Company C. If the number of female employees at Company C increased by 60 percent from 1997 to 1987, by what percent did the number of female employees at Company C increase from 1987 to 1997?

(1) From 1977 to 1997 the number of female employees increased by 200 percent at Company C

(2) In 1977 there were 100 female employees at Company C.


請問原題第一個日期1997是不是改成1977
第二個日期改成1977-1987

條件2日期為1997

請教各位大大 謝謝

我覺得應該將1997 to 1987改為1977 to 1987即可
既然是increase應該1977 to 1997 逐漸增加中比較通順
即題目第一句話 1997 有300 female
條件二說1977 有100個female

然後答案是D吧...
