we are looking for the ratio of r to s. In order to find out the ratio we have to know the value of r and s.

statement 1: r=3(s+1). not sufficient as we don't know the value of s here.
statement 2: 1.2r / 3.6 s = 3/2

12r/36s=3/2
r/s=9:2

so, the correct answer will be B.

(1) r = 3(s + 1)
We cant find the ration here, because it does depend on the actual value of r or s.
For example if s = 1, r = 6, hence r:s = 6
whereas, if s= 100, r = 303 , ratio r:s = 303:100
Hence insufficient.

(2) The ratio of 1.2r to 3.6s is 3 to 2.
$$1.2r/3.6s = 3/2$$
$$r/s= 9/2$$ . Suffcient.
