<result>C</result>
the population of a village is 13400. it increases annually at the rate of 21 % p. a. what will be its population after 2 years?
multiply(13400, power(add(const_1, divide(21, const_100)), 2))
"formula : ( after = 100 denominator ago = 100 numerator ) 13400 × 121 / 100 × 121 / 100 = 19619 c"
