The population of a village decreases every year at the rate of 3%. If the present population is 28227, what was the population of the village two years ago? |
31868 30000 32472 30560 |
30000 |
Population 2 years ago = x x × \(\frac{97}{100}\) × \(\frac{97}{100}\) = 28227 x = 28227 × \(\frac{100}{97}\) × \(\frac{100}{97}\) x = 30000 |
