Detailed Solution
Download Solution PDFGiven:
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.
