ok,
The whole point of the significant figures rules is to avoid indicating a higher degree of accuracy than is actually present.

You could argue that the problems have been expressed in a slightly lax way with respect to the significant figures "rules"

However, I think that they still satisfy the key issue,
which is avoiding indicating an inappropriate level of accuracy.

I think it is one of those situations where if you just follow the rules, without appreciating their proper purpose, one can loose sight of the appropriate answer.
