SSC CGL 202011)The population of a city increased by 30% in the first year and decreased by 15% in the next year. If the present population is 11,050, then the population 2 years ago was:
10,000
Let 2 years ago the population of a city be x.
Population after 1 year =\( x \frac{130}{100}\) = 1.3x;
Population after 2 year = \(1.3x \frac{85}{100}\) = 1.105x;
11050 = 1.105x;
x = 10000
