Explanation / Answer

a) converting 316 to binary

100111100

d)

Binary addition works in the same way, except that only 0's and 1's can be used, instead of the whole spectrum of 0-9. This actually makes binary addition much simpler than decimal addition, as we only need to remember the following:

0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 10

1011
+1110
11001

12) A is a knave and B is a knight is the answer

Because If A is a knight, he wont say both of us are knaves

An since he is a knave he is lying that B is also a knave. So, B must be a knight
