@ Ram:
The answer to Q3 is f(x,y)=x(1+y)
For Q2 any function like f(x,y)= 4x/(-y) or 10*e^x/(-e^y) will satisfy the constraints mentioned. And my answer to the second part would be no. As you change it from non decreasing to non increasing the function would change to f(x,y)= (-x)/y
But they have said a unique function, but here as you can see that you can put plenty of functions.... So there might be some other catch to it...
