Answer 2

ok

Answer 3

1<x-y<-1 ?

Answer 4

1<x-y<1

Answer 5

2<x<4
1<y<3
add:
3<x+y<7
upper limit for x+y is 7.

What is the lower limit for x - y?
The minimum of (x-y) occurs when x is smallest and y is the biggest.
2-3 = -1
minimum of (x-y) is -1.

The ratio will be 7/(-1) = -7.
So I think the answer is none of the above.
