真難過, 這樣簡單卻沒仔細做題
163. 16419-!-item-!-187;#058&011075
In a certain election, 240 men and 280 women voted for the winning candidate. What was the total number of men and women who voted in the election?

起出我以為要考慮沒有去投票的人數, 不過看了一下答案, 似乎不需要考慮沒有去投票的人數. 一時腦筋轉不過來.

(1) The number of women who voted was 7/8 the number of men who voted.
假設男性有去投票的是X人(包含投給勝選與敗選), 女性有去投票的是7/8X人(包含投給勝選與敗選).
insufficient
(2) Of the men and women who voted, 30 percent of the men and 40 percent of the women voted for the winning candidate.
在男性和女性有去投票的人中, 30%男性投給勝選候選人, 40%女性投給勝選候選人
30% * TM(Total Men) = 240 根據題意 , 得TM = 800男性有去投票
40% * TW(Total Women) = 280, 得TW = 700女性有去投票
800+700=1500人有去投票(所有從頭到尾有去投票的男人+女人的數)

我考慮到有權去投票卻沒去的人固然沒有錯, 但是本堤完全沒討論這件事, 我想太多了. = ='''
