Answer:
Measuring national income is difficult in developing countries like Nepal due to several reasons. Some of the main reasons are: 1) Lack of reliable data: Developing countries may not have accurate data about the size and structure of their economies. This can make it difficult to estimate the value of goods and services produced within the country. 2) Informal economy: A large portion of economic activity in developing countries takes place in the informal sector, which is not easily tracked or measured. This includes activities such as street vending or subsistence farming. 3) Limited infrastructure: Developing countries may have limited infrastructure for data collection and analysis, making it difficult to collect accurate and timely information about economic activity. 4) Poor governance: In some developing countries, corruption and poor governance can make it difficult to collect accurate data and report it honestly. 5) Cultural differences: Cultural differences can also make it difficult to accurately measure national income
