The annual rent collected by a corporation from a certain building was x percent more in 1998 than in 1997 and y percent less in 1999 than in 1998. Was the annual rent collected by the corporation from the building more in 1999 than in 1997?
(1) x > y
(2) xy/100 < x - y

lets assume that rent in 97 was $100.
hence rent collected in 98 = 100+x and collected in 99 = 100+x-y-xy/100.

now a is not sufficient but b is clearly sufficient.
