Answer 2

Step-by-step explanation:

The population after 5 years using the formula of S. I. :-

$\sf = \frac{ \cancel{770} \cancel{00} \times 11 \times 5}{ \cancel{2} \times 1 \cancel{00}} \\ \sf = 385 \times 11 \times 5 \\ \sf \: = 21175 \:$

After 5 years the population will be :

77,000 + 21,175 = 98,175 ans.
