Lin the Raccoon went to the MathForces store for pencils. The store sells pencils in a package for $ x $ pieces and $ y $ pieces. It turned out that Lin could not buy 899 pencils, but he could buy any more amount of pencils (having an infinite supply of money). For how many different pairs of $ (x, y) $ is this possible if it is known that $ x < y$?
