OG数学题求教，有没有可能是OG答案错了？

Mary's income is 60 percent more than Tim's income, and Tim's income is 40 percent less than Juan's income.What percent of Juan's income is Mary's income?

A124%
B120%
C96%
D80%
E60%
解题思路没有问题，设T收入1，M为1.6，J为1÷0.6，所以J比M应该是1÷0.6÷1.6=105%，无答案
OG答案为M=1.6*0.6J，Mary's income is 96 percent  of J's income，分析也没错，问题是，题干问What percent of Juan's  is Mary's income?，而答案Mary's income is 96 percent  of J's income，我晕了，J比M和M比J到底哪个比哪个，该怎么表达？是我理解错了题干么？

What percent of Juan's income is Mary's income?
楼主，这句话的意思就是Mary's income is what percent of Juan's

Mary's income is 60 percent more than Tim's income ---> 1.6T = M

Tim's income is 40 percent less than Juan's income. ----> 5/3T = J

What percent of Juan's income is Mary's income ----> x%J = M ----> M/J =?

1.6T/(5/3)T = 0.96

或者你可以用数字算　（我个人觉得会快一点）

J = 100, T = 60, M = 96 ... 96/100 = 96%

Oh 对了 如果你对解题有困难用这 --- is 是 = (等于）.... what 是 Y （ 未知 ） 。。。。of 是 x (相成）

What percent of Juan's income is Mary's income  --> Y (what %) * (of ) J = (is) M
