the population of a city increases by 9 % per year but due to migration it decrease by 1 % per years . what will be the percentage increase in population in 3 years ?
"actual increase in population = 8 % let , earlier population = 100 then the population after 3 years = 100 ( 1 + 8 / 100 ) ^ 3 = 125.97 ∴ required percentage = 25.97 % answer : c"
add(divide(multiply(add(const_100, add(divide(multiply(add(const_100, subtract(9, 1)), subtract(9, 1)), const_100), subtract(9, 1))), subtract(9, 1)), const_100), add(divide(multiply(add(const_100, subtract(9, 1)), subtract(9, 1)), const_100), subtract(9, 1)))
