Introduction:
The food problem in a country refers to the issue of ensuring that all its citizens have access to an adequate quantity and quality of food. This is a complex issue that requires a multi-faceted approach to address. Among the various factors that need to be considered, easy access to food grains, increased production and storage of food grains, and the purchasing power of the people are crucial for solving the food problem of a country.

Easy access to food grains:
Easy access to food grains ensures that people can obtain the necessary amount of food they require. This can be achieved through measures such as:

1. Distribution system: Establishing an efficient and well-organized distribution system that reaches every corner of the country, including remote areas, is essential. This can involve setting up fair price shops, rationing systems, and utilizing technology to streamline the process.

2. Transportation infrastructure: Developing a robust transportation infrastructure is crucial for the timely and cost-effective movement of food grains from production centers to consumption areas. This includes improving road networks, railways, and storage facilities in key locations.

3. Eliminating middlemen: Reducing the involvement of middlemen in the food supply chain can help in making food grains more affordable for consumers. By eliminating unnecessary intermediaries, the prices can be kept in check, ensuring that the grains are accessible to a larger population.

Increased production and storage of food grains:
To meet the growing demands of a growing population, it is necessary to focus on increasing the production and storage of food grains. This can be achieved through the following measures:

1. Agricultural reforms: Implementing agricultural reforms that promote modern farming techniques, use of advanced technology, and efficient irrigation methods can help enhance the productivity of the agricultural sector.

2. Research and development: Investing in research and development in the field of agriculture can lead to the development of high-yielding crop varieties, improved farming practices, and innovative storage techniques.

3. Storage infrastructure: Developing adequate storage facilities such as warehouses, silos, and cold storage units is essential to prevent post-harvest losses and ensure a steady supply of food grains throughout the year.

Purchasing power of the people:
The ability of people to purchase food grains is a crucial aspect of solving the food problem. This can be addressed through:

1. Income generation: Creating employment opportunities and promoting income-generating activities can help increase the purchasing power of the people. This can be achieved through skill development programs, entrepreneurship initiatives, and job creation in various sectors.

2. Social welfare programs: Implementing social welfare programs such as direct cash transfers, food subsidies, and targeted assistance to vulnerable sections of the society can ensure that everyone has the necessary financial resources to purchase food grains.

3. Price control measures: Implementing measures to control the prices of essential commodities can help in making food grains affordable for all sections of the society. This can be achieved through effective regulation and monitoring of the market.

Conclusion:
In conclusion, to solve the food problem of a country, it is necessary to ensure easy access to food grains, increase production and storage of food grains, and improve the purchasing power of the people. These three factors are interdependent and should be addressed collectively to achieve food security for the entire population. By implementing the necessary measures and policies, a country can work towards mitigating hunger and ensuring that its citizens have access to an adequate and nutritious food supply.
