Answer:
Russia and India are most likely to be considered among the world's most important economies in 2050, together with America, China and Germany.
Step-by-step explanation:
India and Russia, together with China and Brazil, are part of the BRIC group, which encompasses future world economic powers that will compete in the future with the United States on the international stage.
It is estimated that by 2050, India will be the second economic power in terms of absolute nominal GDP, while Russia will be the sixth (China will be the first and America the third).
In terms of nominal GDP per capita, America would continue to retain world leadership, while Russia will be fourth and India, due to its large percentage of population below the poverty line, will be seventeenth.
