Solution to 3.
The bank is open and the laundry is not closed. If the restaurant is open, then the laundry is closed. Either the restaurant or the garage is open, but not both. The laundry is not closed only if the tailor is open. If the bank is closed, the tailor is closed. Therefore, either the tailor is open or the garage is closed.
If we let 'closed' mean 'not open', then the simple statements are:
B = The bank is open.
L = The laundry is open.
R = The restaurant is open.
G = The garage is open.
T = The tailor is open.
Substituting, we get:
B and not-not-L.
If R, then not-L.
Either R or G, but not both.
Not-not-L only if T.
If not-B, not-T.
Therefore, either T or not-G.
These are all all quite easy:
