The market value of a share is 80% of the face value. If the selling price = the market value, what percentage of the selling price is the face value.

Let the face value be 100. The market value = 80% of the face value = 80 The selling price = the market value = 80 Face value in terms of the selling price = face value is 100 / 80 * 100 = 125% of the selling price.
