the output of a factory was increased by 10 % to keep up with rising demand . to handle the holiday rush , this new output was increased by 25 % . by approximately what percent would the output now have to be decreased in order to restore the original output ?
"the original output increases by 10 % and then 25 % . total % change = a + b + ab / 100 total % change = 10 + 25 + 10 * 25 / 100 = 37.5 % now , you want to change it to 0 , so , 0 = 37.5 + x + 37.5 x / 100 x = - 37.5 ( 100 ) / 137.5 = 27 % approximately answer is d"
divide(multiply(subtract(add(add(const_100, 10), multiply(add(const_100, 10), divide(25, const_100))), const_100), const_100), add(add(const_100, 10), multiply(add(const_100, 10), divide(25, const_100))))
