are your sure the question is correct? because both statements cannot give you different values of x. IMO statement II should be y=36. Pls check

S=4,x,y...
each term is product of the previous term and a fixed positive integer, say k.
so x=4k..... y =kx=4k^2.....4th term = 4k^3
so we require to find value of k
1) x=12..
x=4k=12....k=3
4th term = \(3^3*4\)
sufficient
2) y=36..
\(y=k^24=36....k=3\)
4th term = \(3^3*4\)
sufficient
