Answer the following question.
State and explain the law of demand.
उत्तर १
Law of Demand:-
The Law of demand is one of the important basic laws of consumption. Dr. Alfred Marshall, in his book "Principles of Economics", has explained the law of demand as follows.
"Other things being constant the higher the price of the commodity, smaller is the quantity demanded arid lower the Mice of the commodity larger is the quantity demanded."
The law of demand explains the change in the behaviour of consumer demand due to various changes in price. Marshall's Law of demand describes the functional relation between demand and price. It can be expressed as D = f (P) that is demand is a function of price. The relation between price and demand is inverse because the larger quantity is demanded when the price falls and a smaller quantity will be demanded when the price rises. The law of demand is explained with the help of the following schedule and diagram.
Table No. 3.3 = Demand Schedule
|
Price of Mangoes
Per Kg. (Rs.)
|
Demand for Mangoes
(Kg.)
|
| 50 | 1 |
| 40 | 2 |
| 30 | 3 |
| 20 | 4 |
| 10 | 5 |
As shown in the schedule when the price of mangoes is Rs. 5O/- per kg. demand is 1 kg. When the price falls to the level of Rs. 40/- per kg. and demand rises to 2 kg. Similarly, at the price of Rs. 10/- per kg. the demand for mangoes is 5 kg., whereas 4 kg. of mangoes are demanded at price Rs. 20/- per kg. This shows an inverse relation between price and demand.
In this diagram, X-axis represents demand for mangoes, whereas the Y" axis represents the price of mangoes. DD is demand! the curve which slopes downwards from left to right. In other words, its slope is negative because of the inverse relationship between price and demand.
उत्तर २
The law of demand focuses on the basic relationship between the price of the goods and quantity demanded of the good.
According to this law, other things being constant (ceteris paribus), a consumer’s demand shares an inverse relationship with the price of a good and vice versa. In other words, if the income, price of related goods, and taste and preferences of the consumer remain unchanged, then the demand for the good moves in the opposite direction of its price.
उत्तर ३
According to the law of demand, a consumer’s demand shares an inverse relationship with the price of a good and vice-versa, ceteris paribus (other things being constant). In other words, if the income, price of related goods and a consumer’s tastes and preferences remain unchanged, then the demand of a good move opposite to the movement in the price of those goods.

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.
The price elasticity of demand for a good depends on ______ and ______ of the good.

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.
