the population of a city increases by 5 % 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 = 4 % let , earlier population = 100 then the population after 3 years = 100 ( 1 + 4 / 100 ) ^ 3 = 112.4864 ∴ required percentage = 12.48 % answer : d"
add(divide(multiply(add(const_100, add(divide(multiply(add(const_100, subtract(5, 1)), subtract(5, 1)), const_100), subtract(5, 1))), subtract(5, 1)), const_100), add(divide(multiply(add(const_100, subtract(5, 1)), subtract(5, 1)), const_100), subtract(5, 1)))
