the present population of a town is 300 . population increase rate is 10 % p . a . find the population of town after 1 years ?
p = 300 r = 10 % required population of town = p * ( 1 + r / 100 ) ^ t = 300 * ( 1 + 10 / 100 ) = 300 * ( 11 / 10 ) = 330 answer is e
add(300, divide(multiply(300, 10), const_100))
