Re: The workers at a large construction company reported x [#permalink]
there is a shortcut for these kind of questions.
If some value is increased by X% then decreased by Y% then the net effective change will be equal to
X-Y-XY/100
that is if some value(say 100) is increased by 10% then decreased by 10% then the net change will be
10-10-100/100 = -1%
the final value be .99*100 = 99

Hope this helps
