the population of a city increases by 8 % 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 = 7 % let , earlier population = 100 then the population after 3 years = 100 ( 1 + 7 / 100 ) ^ 3 = 122.5043 ∴ required percentage = 22.50 % answer : c"
add(divide(multiply(add(const_100, add(divide(multiply(add(const_100, subtract(8, 1)), subtract(8, 1)), const_100), subtract(8, 1))), subtract(8, 1)), const_100), add(divide(multiply(add(const_100, subtract(8, 1)), subtract(8, 1)), const_100), subtract(8, 1)))
