D - 1/5

S: savins each month
M - monthly pay

12S = 3(M-S)
5S = M
S = M/5

does anyone other than me thinks this question is strange? it took me quite a while to get there... and still now not that sure about my confidence level for such questions.. may be because of the fractions :P

In what level would this question be? 500? 600? 650?

Is it problem if I don't assume monthly payment [as saving is said in fraction so payment is one]
such as:
saving is x fraction
so, total saving of the year 12x
according to the condition 12x = 3(1-x)
12x = 3-3x
12x+3x= 3
15x = 3
x = 3/15 = 1/5 or D ans.
Please help if i did wrong.

Alice’s take-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?

A. 1/2
B. 1/3
C. 1/4
D. 1/5
E. 1/6

Let Alice's monthly take-home pay be \(p\) and her monthly savings be \(s\). Total savings will be \(12s\) and we know that this is 3 times the amount she spends in month which is: \(p-s\). So we have:

\(12s=3(p-s)\) --> \(s=p\frac{1}{5}\)

Answer: D.
