उत्तर
The law of demand was introduced by Prof. Alfred Marshall in his book, ‘Principles of Economics’, which was published in 1890. The law explains the functional relationship between price and quantity demanded.
According to Prof. Alfred Marshall, “Other things being equal, higher the price of a commodity, smaller is the quantity demanded and lower the price of a commodity, larger is the quantity demanded.” In other words, other factors remaining constant, if the price of a commodity rises, demand for it falls and when price of a commodity falls demand for the commodity rises. Thus, there is an inverse relationship between price and quantity demanded. Symbolically, the functional relationship between demand and price is expressed as:
Dx = f (Px)
Where D = Demand for a commodity
x = Commodity
f = Function
Px = Price of a commodity

Price of commodity ‘x’ (₹)
|
|
| 50 | 1 |
| 40 | 2 |
| 30 | 3 |
| 20 | 4 |
| 10 | 5 |
As shown in Table when price of commodity ‘x’ is ₹ 50, quantity demanded is 1 kg. When price falls from ₹ 50 to ₹ 40, quantity demanded rises from 1 kg to 2 kgs. Similarly, at price ₹ 30, quantity demanded is 3 kgs and when price falls from ₹ 20 to ₹ 10, quantity demanded rises from 4 kg sto 5 kgs Thus, as the price of a commodity falls, quantity demanded rises and when price of commodity rises, quantity demanded falls. This shows an inverse relationship between price and quantity demanded.
In X axis represents the demand for the commodity and Y axis represents the price of commodity x. DD is the demand curve, which slopes downward from left to right due to an inverse relationship between price and quantity demanded.

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.

Read the case study and answer the questions 97 to 100:
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.
The demand for Coca-cola is ______ in the present times.

In India, Fixed deposits have long been a favourite investment choice of people, especially senior citizens, as it promise steady returns. It attracts those who are seeking a stable income. But it’s an illusion in the period of inflation. Inflation is the rate at which the general level of prices for goods and services rises, subsequently eroding the purchasing power of money. In simple terms, what money could buy today might not a few years down the line. Fixed deposits are financial instruments offered by banks where you deposit a lump sum amount for a fixed period at a predetermined rate of interest. Consider an investment of Rs 1 crore in a fixed deposit at a 6% annual interest rate and the annual rate of inflation is 5%. By the 10th year your pre inflation return is 1.79 crore, but post inflation it’s just 1.10 crore. The nominal value of investment in fixed deposits may appear to grow, inflation significantly diminishes their real value and purchasing power over time.
