choice:a is the answer
a) all rich men are handsome
exp:
cond:2 All handsome men are fair skinned
cond:7 No fair skinned man who is not handsome is rich
by cond:7 a fair skinned and handsome people can be rich.
so a rich people must be both fair skinned and handsome.
by cond:2 we know that all handsome men are fair skinned.
hence we can say that all rich persons are fair skinned.
hence a is the answer.
to be on the safer side let check the remaining answer too.
b) some rich men are handsome
we conclude in the above para that all rich men are handsome and not some rich men.
hence b is not the answer.
c) some rich men are employed

all handsome are fair skinned.
a fair skinned men is not employed.
hence we cannot deduce this choice.

-->all rich are handsome.
so there is a chance for muscular men to be rich.(we cannot conclude this 100 )

some muscular men are not fair skinned.
-->no fair skinned men are rich.
so some muscular men are not rich.(we can conclude this 100 )
what will happen if all the muscular man fall in to this category.
