Worked Example

Step-by-Step

Let's say a chaiwala makes 10 cups of chai in the morning. --- He sells 6 cups of chai to his customers. --- To find out how many cups are left, we start with the total and take away the sold ones. --- So, 10 cups - 6 cups = 4 cups. --- The chaiwala now has 4 cups of chai left, which is a less quantity than he started with. --- Answer: 4 cups of chai.
