1.	E. (1) The population of a city increases at compounding rate of 8% per year.Find the population in the year 2012 if populatin in the year 2010 was2,50,000.
Answer» Given,Population in year 2010 P = 250000Rate R = 8%Time (n) = 2 years Then, Using compound interest formula A = P(1 + R/100)^nA = 250000(1 + 8/100)^2 A = 250000(1.08)^2 A = 250000*(1.1664) A = 291600 Therefore, Population in year 2012 = 291600

Answer»

Given,Population in year 2010 P = 250000Rate R = 8%Time (n) = 2 years

Then, Using compound interest formula A = P(1 + R/100)^nA = 250000(1 + 8/100)^2 A = 250000(1.08)^2 A = 250000*(1.1664) A = 291600

Therefore, Population in year 2012 = 291600
