Answer 1

Step-by-step explanation:

persent population= 1080000

first year population= 108000× 200/3×1/100

=72000

increased population=108000+72000=180000

second year= 1/6 × 180000=30000

decreased population= 180000-30000=150000

third year population=150000×1/3=50000

increased population= 150000+50000= 200000answer
