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

Considr each month her take home is t,spent amt is c, saved amt is s

hence t=s+c

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.this clearly says 12s=3c => 4s=c

=> t=4s+s=5s => s=1/5 * t => answer=1/5

IMO D
