the present population of a town is 1240 . population increase rate is 4 % p . a . find the population of town after 1 years ?
"p = 1240 r = 4 % required population of town = p * ( 1 + r / 100 ) ^ t = 1240 * ( 1 + 4 / 100 ) = 1240 * ( 26 / 25 ) = 1290 ( approximately ) answer is e"
add(1240, divide(multiply(1240, 4), const_100))
