<output>6_400</output>

<result>A</result>
the population of a town is 10000. it decreases annually at the rate of 20 % p. a. what will be its population after 2 years?
subtract(subtract(10000, multiply(10000, divide(20, const_100))), multiply(subtract(10000, multiply(10000, divide(20, const_100))), divide(20, const_100)))
"10000 × 80 / 100 × 80 / 100 = 6400 answer : a"
