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 20%. By approximately what percent would the output now have to be decreased in order to restore the original output?  Pick one:  A) 20%  B) 24%  C) 30%  D) 32%  E) 79%
Let initial output is O then after 10% increase it will be 1.1O and after 20% increase on this new output the latest output will be 1.1O * 1.20 = 1.32O   Now we have to decrease the output by some percentage so that the new output is same as the starting output (O)   so, 1.32O * (1-x/100)   1.1  * 1.20= 
<gadget id="calculator">  1.1  * 1.20</gadget>
<output>1.32</output>
1.32O   Now we have to decrease the output by some percentage so that the new output is same as the starting output (O)   so, 1.32O * (1-x/100)= O   =&gt; x = 24.24%   So, answer will be 24%
<result>B</result>
