उत्तर
Meaning: -The Law of demand establishes the functional relationship between the Price of a commodity and the quantity of that commodity demanded at different prices, assuming other factors remaining constant.
When the price of a commodity rises, demand for it falls and when the price of the commodity falls, demand rises. So less quantity is demanded at higher prices and more quantity is demanded at lower prices. There exist inverse relationship between price and quantity demanded of a commodity.
Definition: -According to Marshall the law of demand, is defined as “Other things being equal, the quantity of a commodity demanded varies inversely with its price.”
Symbolically, the Law of demand can be expressed as follows:
Dx = f (Px)
Where, D = stands for the demand for commodity X
X stands for the commodity demanded
F stands for function of
Px stands for the price of the commodity X
We can explain this law with the help of a schedule and a diagram.
|
Price (Rs.) |
Quantity Demanded |
| 1 | 50 |
| 2 | 40 |
| 3 | 30 |
| 4 | 20 |
| 5 | 10 |
The Schedule shows that with an increase in Price the quantity demanded is decreasing. It indicates inverse relationship between the two variables price and quantity demanded. When the price is Re. 1 the consumer demand 50 units and when the price rises to Rs. 5 he demands the least that is 10 units.

In the above diagram X-axis represents quantity demanded and Y-axis represents price. Various points from the schedule are plotted on the graph, joint those points we will be getting demand curve. DD is the demand curve which slopes downward from left to right indicating inverse relationship between price and Quantity demanded. This happens when the price is more, demand is less and when price is less, and demand is more.

Read the following news report and answer the Q.97-Q.100 on the basis of the same:
The quantity of a commodity that a consumer is willing to buy and is able to afford, given the prices of goods and the consumer's tastes and preferences is called demand for the commodity. Whenever one or more of these variables change, the quantity of the good Chosen by the consumer is likely to change as well. The relation between the consumer's optimal choice of the quantity of a good and its price is very important and this relation is called the demand function. Thus, the consumer's demand function for a good gives the amount of the good that the consumer chooses at different levels of its price when the other things remain unchanged.
Assertion: The income of the consumers remains unchanged
Reason: Commodity should be a normal good.
Select the correct alternative from the following.

The Coca-Cola Company is an American multinational beverage company, with its headquarters in Atlanta, Georgia. The first company that conducted its operation in the soft drink industry was Coca-Cola. It is the world's largest non-alcoholic beverage company serving more than 1.8 billion consumers daily in more than 200 countries. It has a portfolio of more than 3,500 (more than 800 no or low-calorie) products. However, the company is best known for its flagship product Coca-Cola which was originally intended to be a patented medicine invented in 1886 by pharmacist John Smith Pemberton in Columbus, Georgia. The Coca-Cola products can be termed as normal goods and in August 2019 Coca-Cola introduced a new product into the market, that is, zero sugar where the demand has increased for the product in the market.
According to the council of the Australian Food Technology Association and Institute of Food Science and Technology, the Australian nonalcoholic beverages industry has been growing steadily, with a 2.3 percent increase in overall production in the year 2000 which amounts to 2.25 billion liters. However, in the re~ent years, sales of customary carbonated soft drinks have dropped as more and more customers become health conscious and move away from high-calorie sugary drinks. Soft Carbonated drinks. and other alcohol-free beverage manufacturers have also sensed the effects of intensifying competition from private-label soft drink makers. Nevertheless, sales of greater value energy and sports drinks have driven profit generation in the industry.
