Lets make a table from the information we have
First from 8th statement, than 9th, 14th.

Now from 4th statement, Green house is left to the white house so it can be either house 3 or house 4 but we also know from 5th that owner of green house drinks coffee, so it can’t be house 3 (as owner of house 3 drinks milk). thus house 4 is green house and house 5 is white house.
| House 1 | House 2 | House 3 | House 4 | House 5 | |
| Color | Blue | Green | White | ||

Now from statement 3 and 12, we can say that those statements can fit in either house 2 or house 5, so we can say house 2 and 5 either drinks tea or beer but not water, thus house 1 drinks water, and process statement 15th. now we can say house 5 smokes blue master and drinks beer from statement 12. and Danish guy lives in house 2 and drinks tea.
