I have posted this before. However, I use a manual method.
I think there might be a binomial theorem method, and I wonder
if someone can point out. Thanks.

The question is Column A >, < or = to Coulmn B.

Maybe I'm being thick and missing something, but isn't it patently obvious that column B is greater?

anand ...

why wouldn't you have the combinations you have under B, eg. 115 or 511 and similar, under A?? all the combinations under B satisfy the criteria for A and vice versa and so they are both equal.

Your question completely went over my head. Are you saying combination 115 is same as 511. I believe they should be different.
Also I thought under rule A one person should receive atleast $3 and under B one person should receive atleast$1. If not so then I have not understood the question corectly.

tzec--

Why use any theorem? Common sense should tell you that there's no way that the money can be distributed without at least someone getting \$3...

Of course, it took me a minute, but in retrospect, it's terribly obvious.

Please accept my apologies. I thought total of seven dollars have to be distributed instead of seven one dollar bills. What a terrible mistake. It is 11:40 PM after doing reading comprehension on humanities and literature.
You know how it can be to a science/engineering person. I need to sleep now.

Have a good weekend .. and enjoy India's good batting form in the ongoing test match .. if you follow cricket

Revisiting an old problem:

So there is no other way but to do this manually?
