**Reiny**, Thursday, July 19, 2012 at 2:24pmI will assume that 20% of the original, and 5% of the original.

let the number he had be n

so now he has 75% of x left or 3x/4

of those he sold 45%, leaving him with 55% of the remaining

(55/100)(3x/4) = 33

times 400

165x = 13200

x = 13200/165 = 80
