a sells a bicycle to b at a profit of 30 % and b sells it to c at a loss of 20 % . find the resultant profit or loss .
the resultant profit or loss = 30 - 20 - ( 30 * 20 ) / 100 = 4 % profit = 4 % answer is b
multiply(subtract(multiply(add(const_1, divide(30, const_100)), subtract(const_1, divide(20, const_100))), const_1), const_100)
