Question

A coffee machine has 30 litres of water. 15 ml of water is required to prepare a cup of coffee. How many cups of coffee can be made with 30 litres of water?

• A. 1500
• B. 200
• C. 2000
• D. 20000

Answer 1

The correct option is C 2000

Quantity of water in the coffee machine = 30 litres
$(\because 1\text{litre}=1000\text{ml})$
= $30\times 1000$ ml
= 30,000 ml

Given: 15ml of water is required for each cup of coffee.

$\therefore$ Number of cups of coffee that can be made with 30 litres of water
= 30000 ÷ 15
= 2000
