The face value of a share is revalued from 80 per share to 100 per share. If the market value is 75% of the face value and the selling price is 200% of the market value, find the change in the selling price.

The initial face value = 80 rupees The initial market value = 75% of 80 = 60 rupees The initial selling price = 200% of the market value = 120 rupees The changed face value = 100 rupees The changed market value = 75% of 100 = 75 rupees The changed selling price = 75% of the market value = 150 rupees The difference in selling prices = 150 – 120 = 30 rupees.
