1.	The population of a town is 10,000. It increases by 10% during the firstyear. During the second year, it decreases by 20% and increased by30% during the third year. What is the population after 3 years?
Answer» Given,Starting population = 10000 Population after first year= 10000(1 + 10/100)= 10000(11/10)= 11000 Population after second year= 11000(1 - 20/100)= 11000(4/5)= 22004= 8800 Population after third year= 8800(1 + 30/100)= 8800(13/10)= 88013= 11440 Therefore, Population after 3 years = 11440

Answer»

Given,Starting population = 10000

Population after first year= 10000(1 + 10/100)= 10000(11/10)= 11000

Population after second year= 11000(1 - 20/100)= 11000(4/5)= 2200*4= 8800

Population after third year= 8800(1 + 30/100)= 8800(13/10)= 880*13= 11440

Therefore, Population after 3 years = 11440
