Quinn is lying .
FEBRUARY SOLUTION
Let a equal the price of apples , b equal the price of bananas , and o equal the price of oranges . Quinn is saying that 7a + 5b = 6o . Ralph is saying that 4a + 9o = 5b . Steve is saying that 6o + 3b = 4a .
Combining Quinn ' s and Ralph ' s statements , we get 11a = -6o . This is impossible .
Combining Ralph ' s and Steve ' s statements , we get 15o = 2b . This is possible .
Combining Quinn ' s and Steve ' s statements , we get 8b = -3a . This is impossible .
This means that either Quinn is lying , or Ralph and Steve are both lying . But there only can be one liar : obviously Quinn .
