    Check below the detailed explanation for the above Reasoning Questions:

    1).All windows are doors (A) → conversion → some doors are windows (I). Hence conclusion I follow. Some keys are locks (I) + No lock is a window (E) = I+E=O = some keys are not windows. Hence conclusion II follows.
    Answer: e

    2).All trains are trucks (A) + (some ships are trucks (I) → conversion →) some trucks are ships (I) = A+I = No conclusions. But the possibility in I exists. Hence conclusion I follow but conclusion II does not follow from the second statement.
    Answer: a

    3).All trains are trucks (A) → conversion → some trucks are trains (I). Hence conclusion I do not follow.
    Again, some trucks are ships (I) + No ship is a car (E) = I+E = some trucks are not cars.
    Hence conclusion II follows.
    Answer: b

    4).All pages are papers (A) + (some letters are papers (I) → conversion →) some papers are letters (I) = A+I = No conclusion. But the possibility in I exists. Hence conclusion I follow.
    Again, No word is a word (E). Hence II follow.
     Answer: e

    5). From I.There is no mention of N. I is not sufficient to answer the question.
    From II.Total no. of boys between Q and N = 50 – (12+17)
    =50 – (12+17)
    = 50 – 29 = 21
    Only II is sufficient to answer the question
    Answer: b

    6). From both I and II
    3 $ 5 6 → flowers are so beautiful
    6 $ 3 # → red flowers are beautiful
    3$ 6 → flowers are beautiful
    Thus, 5 → so
    # → Red
    Answer: e
