Please try to make the titles of your questions more informative. For example, Why does $a<b$ imply $a+c<b+c$? is much more useful for other users than A question about inequality. From How can I ask a good question?: Make your title as descriptive as possible. In many cases one can actually phrase the title as the question, at least in such a way so as to be comprehensible to an expert reader. You can find more tips for choosing a good title here.

I cant understand the downvoting concept. The question seems legible and appropriate. If the issue is only title, instead of downvoting people can refer some good title.

The downvotes are most likely because this question lacks sufficient context. What have you tried? Why is the problem of interest? What techniques are you familiar with? Stuff like that . . .

(i) is true, because if no doctors are lawyers (b), then no lawyers are doctors.
(ii) is true because no doctors are lawyers (b) and all judges are lawyers (a).
(iii) is false, because we only know that all judges are lawyers, but there may exist lawyers that are not judges.
(iv) is false, because, in order to be a judge, one has to be a lawyer (as per (a)), and no doctor is a lawyer (b).
