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.
Answer
is: c
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.
Answer
is: d
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.
Answer
is: a
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.
Answer
is: e
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.
Answer
is: a
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.
Answer
is: e
7). There is no negative statement but both
conclusions are negative. Hence neither I nor II follows.
Answer
is: d
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.
Answer
is: a
9). No lawyer is man (E) + No man is honest
(E) = E + E = No conclusion. Hence conclusion I does not follow.
Again, Some doctors are lawyers (I) + No
lawyer is a men (E) = I + E = O = Some doctors are not man. Hence conclusion II
does not follow.
Answer
is: d
10). Some letters are pages (I) + All pages
are books (A) = I + A = I = Some letters are books. Hence conclusion I follows.
Again, All pages are books (A) à conversion à Some books are pages (I). Hence
