current population = 16000
After one year population = 16000 - 10% of 16000 = 16000 - (10/100)×16000
= 16000 - 1600
= 14400
After second year population = 14400 - 10% of 14400 = 14400 - 1440
= 12960
After third year population = 12960 - 10% of 12960 = 12960 - 1296
= 11664
population in three years will be 11664
other quickest way is each year population is becoming 90% that is .9 of previous year
so after three years population will be 16000 × .9 × .9 × .9 = 11664
