B+W>50000. We don't know individual values of B and W.

St.(1) Since we don't know total of both B and W, so we can't determine if B>W or W>B. Since B is closer to 50000 doesn't tell anything if we don't know about W. Not sufficient.

St.(2) Since we don't know the total, we can't determine because we cannot get the difference between B and 35000 or between B and W.Not sufficient.

Together if B is closer to 50000 then B can be 49000 or 29000. If B is 49000 then 49000 - 35000=14000 but since we don't know the total we can't determine the difference between B and W because we don't know W.
