If some queens are king and all queens are beautiful so all the kings should be beautiful.

Ya, Arpit is right. All the kings must be beautiful.

How can all kings are beautiful? when the word king is not distributed in the given statement.

Only some kings are queens and not all so all kings can't be beautiful.

For sure all kings must be beautiful. Logically, they inherit this attribute from queens.

SOME kings are queens.

ALL queens are beautiful.

This doesn't mean that ALL the kings are beautiful only the kings who are queens are beautiful.

I don't understand how the 2nd conclusion does not follow, is it because it contains common term queen?, please reply.
