If the original number is 50 and that number increased fourfold, then fourfold means: 4 X original amount = 4 X 50 = 400% of the original amount = 400/100 X original amount = 200. Number 2) is correct and number 1) is not (never) correct.

"fourfold" means 4 times; how you interpret that could mean 1) or 2)! I'd say 2) is more correct.

the mean of that saying is not easy to understand clearly, but i see it as this way: the output of this time has increased 4 times if you compare it with the last year.
