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. At least some forces are strengths.
II. All energies are strengths.

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

Answer 1

The correct option is E Both conclusions I and II are true

Some forces are energies + All energies are powers + All powers are strengths = I + A + A = (I + A) + A = I + A = I = Some forces are strengths (Atleast some forces are strengths). Therefore, conclusion I follows. Again, All energies are powers + All powers are strenghts = A + A = A = All energies are strengths. Therefore, conclusion II follows.

So, both conclusions I and II follow.
