Multiple choice

There are two containers of the same volume, first container half-filled with sugar syrup and the second container half-filled with milk. Half the content of the first container is transferred to the second container, and then the half of this mixture is transferred back to the first container. Next, half the content of the first container is transferred back to the second container. Then the ratio of sugar syrup and milk in the second container is

  1. 5 : 6

  2. 5 : 4

  3. 6 : 5

  4. 4 : 5

AI explanation

Assign each container a capacity of 2 units, meaning the first container holds 1 unit of syrup and 0 units of milk, while the second holds 0 units of syrup and 1 unit of milk. After transferring half from the first to the second, the second container holds 0.5 units of syrup, 1 unit of milk, and 1.5 units total. Transferring half back leaves 0.75 units of syrup in the second container, and the subsequent transfer brings its final syrup to 1.25 units and milk to 1.5 units, yielding a ratio of 5 to 6.
