Elementary Theory of Demand — Economics STD 10 — Question

Table shows that the household will demand more sugar at a lower price, other things being equal. For instance, when price is ₹ 30 per kg, he demands only 1 kg of sugar but, at ₹ 29, he is prepared to buy 2 kg, at ₹ 28 per kg, 3 kg of sugar and so on. This shows that price and demand are inversely related.

Price of suger ₹ (per kg)	Demand by consumer A (kg per month)	Demand by consumer B (kg per month)	Demand by consumer C (kg per month)	Market Demand (kg per month) A + B + C
30	1	2	3	6
29	2	3	4	9
28	3	4	5	12
27	4	5	6	15
26	5	6	7	18

Market Demand Schedule: Market demand schedule shows the quantities of a given commodity which all individual households in the market would demand at different prices. In other words, when the individual demand schedules are added. together, we get market demand schedule. Suppose there are only three consumers A, B and C in the market whose individual demand schedules are given in table 2.1. Market demand schedule has been constructed by adding these individual schedules in the example.
