Brain Teaser...I need the extra credit
 
My teacher periodically gives us these math teasers that are kinda fun to reason through so I post them on 2+2 to give you guys something other than poker to talk about.
Here we go:

Clark, Jones, Morgan, and Smith are four men whose occupations are butcher, druggist, grocer, and policeman, though not necessarily in that order.
a) Clark and Jones are neighbors who take turns driving each other to work.
b) Jones makes more money than Morgan does.
c) Clark beats Smith regularly at bownling.
d) The butcher always walks to work.
e) he policeman doesn't live near the druggist
f) the only time the grocer and the policeman ever met was when the policeman arrested the grocer for speeding.
g) the policeman makes more money than the druggist or grocer.

what is each man's occupation?

good luck guys

I got the same. I guess it's out now in black text.

Butcher dosen't drive, so he must be one of M or S.
Police and grocer don't know each other, so possible police/grocer combos are CM, JS, and JM. MS is not a possible police/grocer combo since one of M or S must be the butcher.
The druggist must be one of C or J, as one of MS is a butcher and the other is a grocer or policeman.

If the druggist is J, then CM is the combo and M must be a policeman or butcher. M cannot be policeman as he would then make more money than J, and M cannot be a grocer as this would make C a policeman, and the policeman does not live near the druggist. Therefore the druggist must not be J: C is the druggist.

J cannot be the policeman as the policeman does not live near the druggist. Therefore one of M or S is the butcher, and one is the policeman. This means that J must be the grocer..

M can now not be the policeman, as he would make more money than J. Therefore M is the grocer

The only one remaining: S is the policeman
