the output of a factory is increased by 10 % to keep up with rising demand . to handle the holiday rush , this new output is increased by 30 % . by approximately what percent would the output of the factory now have to be decreased in order to restore the original output ?
take it as original output = 100 . to meet demand increase by 10 % , then output = 110 . to meet holiday demand , new output increase by 30 % then output equals 143 to restore new holidy demand output to original 100 . final - initial / final * 100 = 43 / 143 * 100 = 30 % approxiamately . option c is correct .
multiply(divide(subtract(multiply(divide(add(const_100, const_10), const_100), divide(add(const_100, 30), const_100)), const_1), multiply(divide(add(const_100, const_10), const_100), divide(add(const_100, 30), const_100))), const_100)
