After the transfer of cards from Quincy to Patrick, the total stays constant.

[[model:questions/solutions/q5386.png]]

• Original: Patrick = 7 units, Quincy = 4 units
• After transfer: Patrick : Quincy = \(2 : 1\)
• Total stays constant at \(7 + 4 = 11\) units
• New Patrick = \(\frac{2}{3} \times 11 = \frac{22}{3}\) units
• New Quincy = \(\frac{1}{3} \times 11 = \frac{11}{3}\) units

Final Answer: 2 : 1
