The correct answer is (a) 27 years.
The Census Projection Report shows that India is one of the youngest nations in the world, with an average age of 27 years in 2020. This is due to the country’s high fertility rate and young population. The report also projects that India’s population will continue to grow in the coming decades, reaching 1.5 billion by 2030. This growth will be driven by a number of factors, including a decline in mortality rates and an increase in life expectancy.
The young population of India is a major asset for the country. It has the potential to drive economic growth and innovation. However, the government will need to invest in education and healthcare to ensure that this potential is realized.
The other options are incorrect because they are not the average age of Indians in 2020. Option (b) is 28 years, option (c) is 29 years, and option (d) is 30 years.
