if the annual increase in the population of a town is 10 % and the present number of people is 10000 , what will the population be in 2 years ?
"the required population is = 10000 ( 1 + 10 / 100 ) ^ 2 = 10000 * 11 / 10 * 11 / 10 = 12100 answer is a"
multiply(multiply(divide(add(10, const_100), const_100), 10000), divide(add(10, const_100), const_100))
