The population of a town has increased by 5% at the end of the first year and decreased by 4% at the end of second year. If the population at the end of second year was 55,12,248, then the population at the beginning of first year was:
Let population at the beginning of first year be xÂ
Now therefore by given conditions we get :
x(1+5/100)(1-4/100) =55,12,248
solving we getÂ
x =54,68,500
