This seems to be rather common GRE Exam Question
Which appears to harder that what it is
It looks like a similar triagle solution
$\dfrac{800}{7000}=\dfrac{x}{1400}$

800/7000 = x/1400
It's a little bit of smoke.
80/700 = x/1400
8/70 = x/1400
8/7 = x/140
8/1 = x/20
Look easier?
Anyone whose first move is to produce 112,000 = 700x simply isn't paying attention.

"Anyone whose first move is to produce 112,000 = 700x" solves problems like this by immediately plugging numbers into a calculator!
