Directions to Solve

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.
Only conclusion I follows
Only conclusion II follows
Either I or II follows
Neither I nor II follows
Both I and II follow
Answer: Option
Since one premise is particular, the conclusion must be particular. So, neither I nor II follows.

How the answer should be neither 1 and 2 follows? Please explain in clear.

When there is no direct relationship between entities of statements or the case is "doubtful, unsure", the possibilities (can be, cannot be, may be) are true.

When the relationship is explicitly or directly mentioned, the possibility is always false.

Why all queens are not kings.

Why doesn't the second statement follows?

Crizy said:   6 years ago
Some queens are kings does not mean that all kings are queens, therefore not all kings are beautiful.

If king and queen are in the same group and if SOME kings are Queens, then all Queens must be kings.

Why not all queens can be kings?

Let's assume, SET(A)=KINGS and SET(B)=QUEENS.

As the given statement say's, "some kings are queens[1], all queens are beautiful[2]"

[1] => SUBSET(A)= SUBSET(B). ---- SUBSET(B) can be a SUPER SET(SUBSET(A)) or SUBSET(A).
So all queens have the possibility to be kings.

Answer: Option D (see here all kings are not beautiful and all queens are not kings).

That here answer (D) : Neither all kings are beautiful nor all queens are kings).

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.
