In each question below are given two statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.

Give answer:

  • (A) If only conclusion I follows
  • (B) If only conclusion II follows
  • (C) If either I or II follows
  • (D) If neither I nor II follows and
  • (E) If both I and II follow.


Statements: Some kings are queens. All queens are beautiful.


  1. All kings are beautiful.
  2. All queens are kings.

[A]. Only conclusion I follows
[B]. Only conclusion II follows
[C]. Either I or II follows
[D]. Neither I nor II follows
[E]. Both I and II follow

Answer: Option


Since one premise is particular, the conclusion must be particular. So, neither I nor II follows.

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.

Some kings are queens.... ok.

It not means all kings are queen.

And all queens are beautiful it means some kings are beautiful.

Anyone explain clearly?

Wil said: (Sat, Jul 25, 2015 09:13:22 AM)    
What it means is, some % all. Since some kings are queens, and all queens are beautiful, only some kings are beautiful, thus I cannot be true. Secondly, since only some kings are queens, logically not all queens can be kings.
