A. 199234
Feedback Initial population is 196000
In First Year, population increasesby 7%
New population
= (107/100) x 196000
= 107 × 196000 / 100
= 107 × 1960
= 209720
Population after 1 year = 209720
In second year, Population decreases by 5%,
New population
= (100 - 5)/100 x 209720
= (95/100) x 209720
= 19 * 10486
= 199234
Population after 2 years will be 199234.
