Should we quote % uncertainty to 1SF or 2SF??

Some past paper question says 1 some says 2 I'm confused!

Please help

For example?

wait wtf? well i guess the 2nd pic probably means that your uncertainty value can be half as accurate as the number of sig figs or the most precise value given in the question.
3rd pic follows exactly what i would do

i would look at all the values in the question and the most precise one for example 8700 in this case (2SF) i would put my answer also to 2 SF
i think this is a good method follow

you quote the uncertainty to the number of significant figures of the value with the least significant figures

that's what my teacher told me that's what i was looking for xD
