Answer is (A) i.e. 1/3

Let Elizabeth & Scott get X per month in total
Let Elizabeth get E per month
Let Scott get X-E per month

According to Question,

3E=9(X-E)
E = 3/4 * X

X-E=X/4

Scott/Elizabeth = 1/3

IMO A


take monthly share of elisabeth = E
monthly share of Scott = S

given 3E = 9S

S/E = 3/9 hence A
