Look the answer for this is 5..... it says within 14 hours
so it can be 13 or 12 or anything that the person die of
poison. So if 30 can are there then we will think it as in
binary no. which will give us some combination of "1" and
"0" i.e 11110(total 5 in numbers). let 1 be the mice and 0
be none. so we will be using 5 mice to carry out the work...
where for detecting in this case we have used only four. If
i would have been 33 cans then we would have used 6 mice.
and if 15 then only 4. and so on..... so concept is : think
in term of binary, how could you express the given no in
binary and in total how many 1's and 0's are required. that
will give u the required answer.
