the population of a city increases by 7 % 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 = 6 % let , earlier population = 100 then the population after 3 years = 100 ( 1 + 6 / 100 ) ^ 3 = 119.1016 ∴ required percentage = 9.1016 % answer : b"
add(divide(multiply(add(const_100, add(divide(multiply(add(const_100, subtract(7, 1)), subtract(7, 1)), const_100), subtract(7, 1))), subtract(7, 1)), const_100), add(divide(multiply(add(const_100, subtract(7, 1)), subtract(7, 1)), const_100), subtract(7, 1)))
