Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 851598
In 1st year, growth in population = 12 per thousand i.e.1.2%
Population after 1 year = 850000 + 1.2% of 850000
= 850000 + 10200
= 860200
Population after 2nd year = 860200 - 1% of 860200
= 860200 - 8602
=851598
