For the students in Class A, the range of their height is r cm and the greatest height is g cm. For the students in Class B, the range of their heights is s cm and the greatest height is h cm. Is the least height of the students in Class A greater than the least height of the students in Class B?

(1) r <s> h

Need to repost.

So far though: let x equal the smallest in A and y equal teh smallest in B.

Thus A's range is: g-x=r

B's range is: h-y=s

So the real question here is, is x>y?

So far i don't think S1 is suff.
