Answer 1

`21.9 * 10^(10)` Population of the Country Now .

Explanation:

According to the Question,

• Given, A small country had a population of
  `7.1 * 10^(10)` in 1990. Since then, the original population has doubled Thus The Population as of Now is
  `2*7.1 * 10^(10) =`
  `14.2 * 10^(10)`
• And
  `7.7 * 10^(10)` people have immigrated into the country Thus, The New Population of the Country is
  `14.2 * 10^(10) + 7.7 * 10^(10) =`
  `21.9 * 10^(10)` .
