If 650 invested in stocks, and 400 invested in stocks and bonds, then 250 invested in stocks only.
650 invested in stocks, 550 in bonds, and 400 in both. Thus 650+550-400, which gives us 800, invested in either stocks or bonds.
If 800 out of 1000 invested in some way, then 200 didn't invest in either stocks or bonds..
