Question

A water container has 19.5 litres of water in it. A cup holds 210 ml of water. At most 92 cups can be filled completely from the water container. Explain why

Answer 1

Explanation:

Given

A container has 19.5 liters of water

A cup can hold 210 ml of water

1 L is equivalent to 1000 ml

So, 19.5 L is equivalent to
`19.5* 1000=19,500\ ml`

So, the number of requires to hold this much water

`\Rightarrow n=(19,500)/(210)\\\\\Rightarrow n=92.85\ \text{cups}`

92.85 implies 92 full cups and 1 cup which is partially filled. Hence, almost 92 cups can be filled completely.
