Check below the detailed explanation for the above Reasoning Questions:

1). Some biscuits are chocolates (I) + No chocolate is a pastry (E) = I + E = O = Some biscuits are not pastries. Hence conclusion I does not follow.
Again, Some biscuits are not pastries (O) + All pastries are cakes (A) = O + A = No conclusion. Hence conclusion II does not follow.
Again, No chocolate is a pastry (E) à conversion à No pastry is a chocolate (E). Hence conclusion III follows.

2). Some jeeps are scooters (I) + All scooters are motorcycles (A) = I + A = I = Some jeeps are motorcycles. Hence conclusion I follows.
There are not negative statements. Hence the possibilities in II and III exist. Hence conclusion II and III also follow.

3). Some books are papers (I) + All papers are pencils (A) = I + A = I = Some books are pencils. Hence conclusion II follows.
Now, Some books are pencils (I) + Some pencils are copies (I) = I + I = I = No conclusion. Hence conclusion I does not follow.
Again, All papers are pencils (A) + Some pencils are copies (I) = A + I = No conclusion. Hence conclusion III does not follow.

4). No cat is a dog (E) + Some dogs are camels (I) = E + I = O* = Some camels are not cats. Hence conclusion I follows.
Nor does conclusion II follow.
Again, Some dogs are camels (I) + No camel is a rat (E) = I + E = O =Some dogs are not rats. Hence conclusion III does not follow.

5). There is no negative statement. Thus the possibility in I exists. Hence conclusion I follows.
Again, Some numbers are alphabets (I) + All alphabets are vowels (A) = I + A = I = Some numbers are vowels. Hence conclusion II follows.
Again, All digits are numbers (A) à conversion à Some numbers are digits (I). Hence, conclusion III follows.

6). All engineers are cooks (A) + Some cooks are merchants (I) = A + I = No conclusion. But the possibility in I exists. Hence conclusion I follows.
Again, Some cooks are merchants (I) à conversion à Some merchants are cooks (I). Hence conclusion II follows.

7). There is no negative statement but both conclusions are negative. Hence neither I nor II follows.

8). Some doctors are lawyers (I) + No lawyers is a man (E) = I + E = O = Some doctors are not men Hence conclusion I follows.
No lawyer is a man (E) + No man is honest (E) = E + E = No conclusion. Hence conclusion II does not follow.
