A machine cost £40,000 on 1 January 20X7. The reducing balance depreciation method is used at 25% per annum. Year end is 31 December. During 20X9, it was decided that a straight line method would be more appropriate. At that time, the remaining useful economic life of the machine was seven years with a residual value of £1,500.

Required:
