Answer 1

Greetings...!!

Population before two years = 4000

Population increase  during next = 6% = 6% of 400 = (6/100)*4000=240

New population = Previous + Increase = 4000+240=4240

Decrease in population in following year = 5% = 5% of 4240=(5/100)*4240=212

New population = Previous - Decrease = 4240-212=4028

Answer : Thus,present population is 4028.
