The face value of a share is revalued from 1000 per share to 2000 per share. If the market value is 50% of the face value and the selling price is 400% of the market value, find the change in the selling price.

The initial face value = 1000 rupees The initial market value = 50% of 1000 = 500 rupees The initial selling price = 400% of the market value = 2000 rupees The changed face value = 2000 rupees The changed market value = 50% of 2000 = 1000 rupees The changed selling price = 400% of the market value = 4000 rupees The difference in selling prices = 4000 – 2000 = 2000 rupees.
