Q31
The total quantity of a commodity that all producers are willing and able to sell at a specific price during a given period is known as:
Market supply
Individual supply
Aggregate demand
Market stock
Explanation
Market supply represents the aggregate sum of the individual quantities supplied by all sellers in the market at a given price level.
Q32
If the price of wheat rises significantly, what is the likely impact on the supply curve of mustard, assuming they are competitive crops for the same farmland?
It shifts leftward
It shifts rightward
It causes a downward movement along the same curve
It remains entirely unchanged
Explanation
A rise in the price of a competitive alternative good (wheat) makes it more profitable, prompting farmers to shift land away from mustard, shifting the mustard supply curve leftward.
Q33
Which of the following is considered a determinant of individual firm supply but NOT directly a determinant of market supply structure?
An individual firm's specific objective
Total number of firms in the industry
Market distribution infrastructure
Average consumer preferences across the region
Explanation
An individual firm's specific goal (e.g., profit maximization vs sales maximization) directly dictates its individual supply, whereas things like the total number of firms specifically determine aggregate market supply.
Q34
A graphical representation showing the relationship between the price of a good and the quantity supplied by a single producer is called an:
Individual supply curve
Market supply schedule
Individual demand curve
Market supply curve
Explanation
An individual supply curve graphically plots how a single firm adjusts its output quantities in response to varying price levels.
Q35
What type of supply relationship exists when a single core input source naturally yields multiple distinct commercial goods simultaneously?
Joint supply
Composite supply
Inelastic supply
Competitive supply
Explanation
Joint supply refers to goods that are derived from a single common source or production process, meaning an increase in the production of one automatically increases the supply of the other.
Q36
Which of the following statements correctly differentiates between 'Stock' and 'Supply'?
Supply is a flow variable derived as a part of stock, which is a stock variable.
Stock is always equal to supply in the long run for all commodities.
Supply is always greater than stock for non-perishable goods.
Stock depends on price while supply is independent of price.
Explanation
Stock is the total volume of a commodity available with a seller at a point in time, whereas supply is that part of stock which a seller is willing to offer for sale at a specific price during a specific period.
Q37
For highly perishable goods like fresh milk or green vegetables, the short-run supply curve tends to be:
Highly inelastic
Perfectly elastic
Downward sloping
Unitary elastic
Explanation
Perishable goods cannot be stored for long. Sellers must sell them off quickly even if the price falls, making the immediate or very short-run supply highly inelastic.
Q38
Given the linear supply function Qs = -20 + 4P, what is the quantity supplied when the market price is ₹15?
40 units
80 units
20 units
60 units
Explanation
Substitute P = 15 into the function: Qs = -20 + 4(15) = -20 + 60 = 40 units.
Q39
From a given supply function Qs = -a + bP, what does the coefficient 'b' mathematically represent?
The change in quantity supplied per unit change in price
The price elasticity of supply at equilibrium
The autonomous supply independent of price factors
The total overhead cost incurred by production units
Explanation
The coefficient 'b' measures the change in quantity supplied per unit change in price, which is the slope of the supply function with respect to price.
Q40
If a regulatory body introduces a mandatory price floor above the market equilibrium price, what will be the immediate impact on the market supply side?
An extension of quantity supplied leading to excess supply
A contraction of quantity supplied leading to a shortage
A leftward shift of the market supply curve
A complete collapse of producer surplus metrics
Explanation
A price floor set above equilibrium causes an extension of supply along the curve as producers look to capitalize on higher forced prices, resulting in market surplus.
