the present population of a town is 220 . population increase rate is 10 % p . a . find the population of town after 1 years ?
"p = 220 r = 10 % required population of town = p * ( 1 + r / 100 ) ^ t = 220 * ( 1 + 10 / 100 ) = 220 * ( 11 / 10 ) = 242 answer is d"
add(220, divide(multiply(220, 10), const_100))
