What do you mean by xD ?

Let flat A have be 3x
flat B 4x then
flat C = 4x

and flat D = 3x+95

The total is 275 so
3x+4x+4x+(3x+95) = 275

Solve for x

14x + 95 = 275
14x=180
x= 12.857....
then work out each flats rent.

Flat A = 3x12.857 = 38.571 ...
Flat B = Flat C = 4x12.857... = 51.428....
Flat D = 3x+95 = 3x12.857 ... +95 = 133.571...

Hope that helps
