Agree:

The demand curve typically slopes downward from left to right due to the **law of demand**, which states that as the price of a good decreases, the quantity demanded increases, and vice versa. This negative relationship between price and quantity demanded results in a downward-sloping curve.

However, this is true for most goods but may not hold for certain types of goods such as Giffen goods or Veblen goods.


Final Answer: \[ \boxed{Agree: \; The \; demand \; curve \; generally \; slopes \; downward \; from \; left \; to \; right.} \] Quick Tip: The downward slope of the demand curve reflects the inverse relationship between price and quantity demanded.

N/A Quick Tip: Index numbers are useful but come with limitations such as the choice of base year and data quality.

N/A Quick Tip: The more substitutes a good has, the more elastic its demand will be.

N/A Quick Tip: Exceptions to the law of supply occur in special cases like Giffen goods and markets with limited capacity.

N/A Quick Tip: The capital market supports long-term economic development by connecting investors with businesses in need of funds.

N/A Quick Tip: Market demand is the sum of individual consumers' demands at each price level.

Step 1: Understand the Diagram.

The given diagram represents a non-linear demand curve where the price is plotted on the y-axis and the quantity demanded on the x-axis. There is a point labeled "E" where the demand curve intersects a horizontal price line. Points "d" and "d₁" represent different demand points for the commodity.

Step 2: Answer the Questions.


(1) If EB = EA (Ed = 1) = ........
Answer:
When EB = EA, it implies that the price elasticity of demand (Ed) is 1. Therefore, at point E, the demand is **unitary elastic**.
So, the answer is: \[ \boxed{Ed = 1 \; (unitary elasticity)} \]


(2) If EB > EA (Ed > 1) = ........
Answer:
When EB > EA, it implies that the price elasticity of demand (Ed) is greater than 1. This indicates **elastic demand** where the quantity demanded is highly responsive to price changes.
So, the answer is: \[ \boxed{Ed > 1 \; (elastic demand)} \]


(3) If EB < EA (Ed < 1) = .........
Answer:
When EB < EA, it implies that the price elasticity of demand (Ed) is less than 1. This indicates **inelastic demand** where the quantity demanded is less responsive to price changes.
So, the answer is: \[ \boxed{Ed < 1 \; (inelastic demand)} \]


(4) The ‘x’ axis represents ......... of commodity and ‘y’ axis represents ........ of commodity.
Answer:
The ‘x’ axis represents the **quantity demanded** of the commodity, and the ‘y’ axis represents the **price** of the commodity.
So, the answer is: \[ \boxed{Quantity demanded, Price} \] Quick Tip: Elasticity of demand measures the responsiveness of quantity demanded to price changes: Ed > 1 for elastic demand, Ed < 1 for inelastic demand, and Ed = 1 for unitary elasticity.

(1) Which act regulates the market?

The **Bombay Agricultural Product Market Act-1939** regulates the market. According to this act, the state government controls the wholesale market to ensure fair practices and eliminate malpractices.

Step 1: State the Law of Diminishing Marginal Utility.

The law of diminishing marginal utility states that as a person consumes more units of a good, the satisfaction (utility) derived from each additional unit decreases, while the total utility continues to increase, but at a diminishing rate. In other words, the marginal utility (the utility of consuming one more unit) decreases with each additional unit consumed.

Step 2: Assumptions of the Law.

1. **Constant Conditions**: The consumer’s taste and preferences remain constant while consuming the good.

2. **No Change in the Quality of Goods**: The quality of the good consumed remains the same.

3. **Independent of Other Goods**: The consumption of one good is not affected by the consumption of another good.

4. **Short Time Period**: The consumer is consuming the good within a limited period of time.


Final Answer: \[ \boxed{The \; law \; of \; diminishing \; marginal \; utility \; states \; that \; as \; consumption \; of \; a \; good \; increases, \; the \; additional \; satisfaction \; derived \; from \; each \; extra \; unit \; decreases.} \] Quick Tip: The law applies when each additional unit of a good provides less satisfaction than the previous unit, assuming other conditions remain constant.
