Question

GMAT 数学题一道，求解。 这道题怎么翻译？

A group of 20 friends formed an investment club, with each member contributing an equal amount to the general fund. The club then invested the entire fund, which amounted to d dollars,in Stock X. The value of the stock subsequently increased 40 percent, at which point the stock was sold and the proceeds divided evenly among the members .In the terms of d, how much money did each member of the club receive from the sales (Assume that transaction fees and other associated costs were negligible)

Answer 1

20个人组成了一个小组，每个人给总基金捐了一样的钱。小组用掉了整个基金的钱（总共 d 美元）来买股票X。 X随后涨了40%，这时这个小组把股票卖了，然后把钱分成等分给每个人。 以d为单位，小组里的每个人最后得到了多少钱（假设没有其他任何费用）
d*(1+0.4)=1.4d
1.4d/20=0.07d
所以答案是0.07d

Answer 2

一道数学题：

每人控股5%，投资5%d 美金
股票卖出时价值为140%d
每人得到其中的5%
等于140%d*5%=7%d 美金
