If we separate and label the clues, and label the bungalows #1, #2, #3, #4 from left to right we can see that:

a. Mrs Scott's bungalow is somewhere to the left of the wooden one.
b. The third one along is brick.
c. Mrs Umbrella owns a straw bungalow
d. Mr Tinsley does not live at either end.
e. Mr Tinsley lives somewhere to the right of the glass bungalow.
f. Mr Wilshaw lives in the fourth bungalow
g. The first bungalow is not made from straw.

By (g) #1 isn't made from straw, and by (b) nor is #3. By (f) Mr Wilshaw lives in #4 therefore by (c) #2 must be straw, and Mrs Umbrella lives there.

Therefore by (d) Mr Tinsley must live in #3, which, by (b) is the brick bungalow.

By (a) #4 must be wooden (otherwise Mrs Scott couldn't be to its left) and by (f) Mr Wilshaw lives there.

Which leaves Mrs Scott, living in #1, the glass bungalow. QED.

These words have had their vowels removed. Can you replace the vowels to make some vegetables:

Digit3 can only be 3, 6 or 9 (as it's 3 x Digit2).

Digit2 can only be 1, 2 or 3.

Digit1 can only be 2, 4 or 6.

But, since Digit4 is two thirds of Digit1, Digit1 must be 6. Making Digit4 4 and making Digit3 9. Making Digit2 3.

Giving 6394. QED.
