Last Sunday, the Stewart Vineyard ran a price promotion in which it sold red wine for r dollars per case and white wine for w dollars per case. What was the ratio of the revenue from red wine to the revenue from white wine?
Let m and n be the number of red wine cases and white wine cases respectively that were sold last sunday.
so we need to find : rm/wn
1) Last Sunday, the Stewart Vineyard sold 4 times as many cases of red wine as it sold of white wine.
this implies that m = 4n
but we do not know the exact values of r and w
Not sufficient
2) Last Sunday, the Stewart Vineyard sold each case of white wine for $50 more than each case of red wine.
this implies that w = r + 50
but we do not know the exact values of m and n
hence not sufficient
statement 1 and 2 together
we get the ratio : rm/{n*(r+50)} = 4r/(r+50) and we cannot proceed further.
Hence, not sufficient
Answer E
