Given:

Total water in the sink = 12 litres.

Remaining water in the sink = 6 litres less than the quantity drained away.

Formula Used:

Let the quantity of water drained away be x litres.

Remaining water in the sink = Total water - Quantity drained away.

Remaining water = x - 6.

Calculation:

Total water - Drained water = Remaining water.

⇒ 12 - x = x - 6.

⇒ 12 + 6 = x + x.

⇒ 18 = 2x.

⇒ x = 18 / 2.

⇒ x = 9 litres.

The quantity of water drained away is 9 litres.
