20 chairs

Let the number of chairs bought=x, then
CP of 1 chair = 10000/x
SP of 1 chair = (10000/x)+50
As he kept 1 chair and sold (x-1) chairs, so total SP=(x-1)*[(10000/x)+50]
Profit = SP - CP = (x-1)*[(10000/x)+50] - 10000 = 450
On simplifying, we get x² - 10x - 200 = 0
=> (x+10) (x-20) = 0
So x=20
