The central problems relating to allocation of resources refer to the fundamental economic questions that arise from scarcity of resources. These problems are faced by all economies, regardless of their level of development. The three central problems are:

1. What to produce?
This problem refers to the challenge of deciding what goods and services should be produced in an economy. This decision is based on several factors, including consumer demand, availability of resources, and technology. In a market economy, this decision is made by the interaction of buyers and sellers in the marketplace. In a planned economy, the government makes this decision.

2. How to produce?
This problem refers to the challenge of deciding the most efficient way to produce goods and services. This decision is based on the availability of resources, technology, and the desired level of output. The choice of production technique can have significant implications for the economy, including the level of employment, the quality of output, and the cost of production.

3. For whom to produce?
This problem refers to the challenge of deciding who will consume the goods and services produced in the economy. This decision is based on several factors, including income, wealth, and social status. In a market economy, this decision is made by the purchasing power of consumers. In a planned economy, the government makes this decision.

In summary, the central problems relating to allocation of resources are what to produce, how to produce, and for whom to produce. These problems are fundamental to all economies and require careful consideration to ensure that resources are allocated efficiently and effectively.
