Start the planI came across this question in the Princeton Review - cracking the GMAT premium 2020 edition .
Here is the original question:
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 20%. By approximately what percent would be the output of the factory now have to be decreased in order to restore the original output?
(a) 20%
(b) 24%
(c) 30%
(d) 32%
(e) 70%
I tried to answer this question by plugging in 1000 as the original output, and i get 32% as my answer. However, the answer provided by this book is 24%, with no any explanation.
Can anyone show how does it get 24%? Why not 32% instead?
Thanks in advance.
