Question 1013776
If I read this right,
{{{ 240/48 = 5 }}}
{{{ 144/48 = 3 }}}
-----------------
It looks like you could have 3 groups with 48 
cans of food and 3 groups with 48 bottles of water
That would give you the most items in each of
the 3 groups. Then there would be {{{ 2*48 - 96 }}}
bottles of water left over
--------------------------
So, the answer would be {{{ 2*48 = 96 }}} ( bottles and cans )
is the largest number of relief supplies that could be put
into each group. 
------------------
Definitely get another opinion on this. It's kind of a strange question.
It sounds like they don't care how many groups there are.
Why would that be?
