数学很烂，今天刚开始看OG就出现问题了~
OG75. Leona bought a 1-year, $10,000 certificate of deposit that paid interest at an annual rate of 8 percent compounded semiannually. What was the total amount of interest paid on this certificate at maturity?
不是很明白这道题目的意思~
Data Sufficiency:
OG7. What percent of a group of people are women with red hair?
1. Of the women in the group, 5 percent have red hair.
2. Of the men in the group, 10 percent have red hair.
我想选A, 因为觉得A与题目表达的意思一样~
各位大侠帮帮忙~呵呵~

题目意思是：Leona有$10,000 ，存1年定期，年利率为8%，半年期复利，问利息共有多少？

题目问某群人中，红头发的女性占几分之几？
(1) 女性中，红头发的占5%。---> 男性或此人群的人数未知，所以不充分
