A lattice point in a plane is a point for which both coordinates are integers. The number of lattice points lies inside the triangle whose sides are,x=0,y=0 and x+y=20 is

A lattice point in a plane is a point for which both coordinates are integers. If n be the number of lattice points inside the triangle whose sides are x=0,y=0 and 9x+223y=2007 then tens place digit in n is:
