Water cooler holds = 50 pt of water

1 L≈1.06 qt (which is the value of US liquid quart)

1.06 qt = 2.12 pt (which is the value of US liquid pint)

So when we are calculating how many liters of water cooler holds, divide the 50pt with 2.12pt

50pt/2.12pt = 23.6 Liters

So 23.6 is the correct answer.
