There are some interventions which are up to 10,000 x better, comparing them to low performing ones, but I don’t think the question is intended this way.
Quote from a GivingWhatWeCan Giving Game Slide:
The best charities can be at least ten times better than a typical charity within the same area, or hundreds of times better than poor-performing charities. Some charities even actively harm those they seek to help.

[...] moving money from the least effective intervention to the most effective would produce about 15,000 times the benefit, and even moving it from the median intervention to the most effective would produce about 60 times the benefit.
I think the question is intended the way that “10 – 100 x times” is the correct answer. But please take a look into the essay from Toby Ord and decide for yourself.
