问一道GMATprep的PS题~~

JuliusYu

Alice's task-home pay last year was the same each month, and she saved the same fraction of her take-home pay each month. The total amount of money that she had saved at the end of the year was 3 times the amount of that portion of her monthly take-home pay that she did not save. If all the money that she saved last year was from her take-home pay,what fraction of her take-home pay did she save each month?

这道题也没读太懂，于是就乱做了  哪位NN帮帮我吖~~

答案是3/4吗?根据题意save=3(takehome-save)

12*x=3*(1-x)
