Three business partners, Q, R, and S, agree to divide their total profit for a certain year in the ratios 2:5:8, respectively. If Q's share was $4,000, what was the total profit of the business partners for the year?
$26,000
$30,000
$52,000
$60,000
$300,000
题目分析：
根据题目可知，三个投资人分红的比例 2:5:8, 其中 Q 占的份额是 2/(2+5+8)=2/15.Q 拿到的分红是 4000,所占的比例 2/15.可以求出总的利润就是 4000÷(2/15)=30000.
综上：答案就是 B
把所有portion加起来，或者求单个portion
