The least-cost combination of inputs is achieved at the point where the isoquant (representing the substitution ratio) is tangent to the iso-cost line (representing the price ratio). At this point of tangency, the slopes of both curves are equal. Mathematically, this condition signifies that the firm is producing its output at the minimum possible cost. If the ratios were not equal, the firm could still reduce costs by substituting one input for another.

When the substitution ratio (marginal rate of substitution) is less than the price ratio, the firm is not at its equilibrium point. It indicates that the last pound spent on one input is providing less marginal return than the last pound spent on another. In such a state, the cost is not minimised; therefore, the current expenditure is higher than it needs to be. (Note: The provided answer 'B' in the prompt suggests the cost is at a 'maximum' relative to the optimal path, though 'not minimised' is the standard economic interpretation).

Unit labour cost is calculated by dividing the total labour compensation by the total output. If workers become 5% more efficient (producing 5% more output in the same time) and their pay increases by exactly 5%, the cost of labour required to produce a single unit of the product remains exactly the same. The increase in pay is perfectly offset by the increase in productivity, resulting in stable unit labour costs.

Income elasticity of demand measures how the quantity demanded changes in response to a change in consumer income. For a luxury good, a 1% increase in income leads to a more than 1% increase in the quantity demanded. In contrast, for necessities, the elasticity is between 0 and 1, meaning demand grows more slowly than income. Inferior goods have a negative income elasticity.

In Co-operative Collective Farming, the society holds the land and all means of production. Members lose their individual identity as far as land ownership is concerned for the duration of the membership. The management is handled by an elected general body or committee, and members work as labourers, receiving a share of the profits based on the work they perform and the resources they contributed.

The Law of Demand describes the inverse relationship between price and quantity. When the price of a good falls, it becomes relatively cheaper compared to other goods (substitution effect), and the consumer's purchasing power increases (income effect). Both of these effects typically lead to an increase in the quantity of the commodity that consumers are willing and able to buy.

A production function that is homogeneous of degree one signifies 'Constant Returns to Scale' (CRS). This means that if all inputs are increased by a factor of \(k\), the output also increases by exactly the same factor \(k\). In this case, the elasticity of scale is equal to 1 (unity). (Note: The provided answer 'D' in the original prompt is incorrect; a degree of one implies unity).

This describes 'Perfectly Inelastic Demand'. In such a case, consumers require a fixed amount of the good (such as life-saving medicine) and will buy that same amount whether the price is high or low. When plotted on a graph with Price on the Y-axis and Quantity on the X-axis, this relationship appears as a straight vertical line.

Price elasticity is calculated as the percentage change in quantity divided by the percentage change in price. If the change in quantity is zero, the numerator is zero, making the entire coefficient zero (\(E_p = 0\)). This signifies perfectly inelastic demand. (Note: The provided answer 'D' in the original prompt is incorrect, as 'Equal to one' describes unitary elasticity).

In Co-operative Joint Farming, small farmers pool their land, labour, and resources to enjoy the benefits of large-scale farming. Critically, each member retains the ownership of their specific plot of land and receives a 'dividend' or 'rent' for its use, in addition to wages for the work they perform. This distinguishes it from 'Collective' farming, where individual land rights are surrendered.
