Question

In these questions two/three statements followed by two conclusions numbered I and II have been given. You have to take the given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusion logically follows from the given statements disregarding commonly known facts.

Statements:-
Some forces are energies.
All energies are powers.
All powers are strengths.

Conclusions:-
I. All forces being powers is a possibility.
II. All powers are energies.

• A. Only conclusion I is true
• B. Either conclusion I or II is true
• C. Only conclusion II is true
• D. Both conclusions I and II are true
• E. Neither conclusion I nor II is true

Answer 1

The correct option is A Only conclusion I is true

Some forces are energies + All energies are powers = I + A = I = Some forces are powers $\to$ All forces being powers is a possibility. Therefore, conclusion I follows. Again, All energies are power $\to$ conversion $\to$ Some powers are energies. Therefore, conclusion II does not follow.

So, only conclusion I follows.
