    Check below the detailed explanation for the above Reasoning Questions:

    1).Some letters are stories (I) → conversion →Some stories are letters (I). Hence conclusion I does not follow. There is no negative statement. Thus the possibility in II exists. Hence conclusion II follows.
    Answer: b

    2).All helicopters are aeroplanes (A) + No aeroplanes is a fan (E)= A + E = E = No helicopter is a fan (E). Hence conclusion I follow.
    Again, No aeroplane is a fan (E) → conversion → No fan is an aeroplane (E). Hence conclusion II follows.
    Answer: e

    3).All locks are computers (A) + (No TV is computer (E) →conversionà) No computer is a TV (E) = A + E = E = No lock is a TV (E). Hence conclusion I follow.
    Again, Some keys are locks (I) + All locks are computers (A) = I + A = I = Some keys are computers (I) + No computer is a TV (E) = I + E = O = Some keys are not TVs. Hence conclusion II follows.
    Answer: e

    4).All locks are computers (A) + No computer is a TV (E) = A + E = E = No lock is a TV → conversion → No TV is a lock → implication → Some TVs are not locks (O). Hence conclusion I follows.
    Again, Some keys are locks (I) + All locks are computers (A) = I + A = I = Some keys are computers. Hence the possibility in II exists. Hence conclusion II follows.
    Answer: e

    5).No star is a planet (E) + (Some birds are planets (I) → conversion →) Some planets are birds (I) = E + I = O* = Some birds are not stars. Hence conclusion I does not follow. Again, No star is a planet → conversion → No planet is a star. Hence conclusion II follows.
    Answer: b
