E plc has an issued share capital consisting of 800,000 ordinary shares. There are no preference shares. Some years ago, the company issued £1 million of 10% convertible loan stock, convertible in 2028 at the rate of two ordinary shares for every £10 of loan stock. The company's profit after tax for the year to 31 March 2024 is £640,000.

Required:
(a) Calculate basic EPS for the year to 31 March 2024.
(b) Calculate diluted EPS for the year to 31 March 2024, assuming that the company pays tax at 20%.
(c) Rework both of the above calculations, now assuming that the loan stock was not issued "some years ago" but was in fact issued on 1 October 2023.
