A sink contains exactly 12 liters of water. If water is drained away from the sink until it holds 6 liters of water less than the quantity drained away, then determine the volume of water that were drained away (in liters)?
Sink = 12 Liters Amount drained =D 12 - D =D - 6 12+6 =2D D =18 / 2 D =9 liters drained out of the Sink
