<result>A</result>
the population of a town increases 20 % and 25 % respectively in two consecutive years. after the growth the present population of the town is 1500. then what is the population of the town 2 years ago?
divide(1500, multiply(add(const_1, divide(20, const_100)), add(const_1, divide(25, const_100))))
"explanation : formula : ( after = 100 denominator ago = 100 numerator ) 1500 * 100 / 120 * 100 / 125 = 1000 answer : option a"
