उत्तर
A demand schedule is a tabular representation showing the quantities of a good or service that consumers (individual demand schedule) or all consumers in the market (market demand schedule) are willing and able to purchase at various prices over a specific period.
It reflects the law of demand, which states that as the price of a good decreases, the quantity demanded generally increases, and vice versa, assuming other factors remain constant.
Example:
A Consumer’s Weekly Demand for Coffee
| Price per cup (in ₹) | Quality Demanded (Cups per week) |
| 4 | 2 |
| 3 | 4 |
| 2 | 6 |
| 1 | 8 |
This table shows that when the price is ₹ 4, the consumer buys 2 cups, but when the price drops to ₹1, the consumer buys 8 cups.
