Hi I have a question on accounting for PPE and recording of Impairments.

So the question goes

Bee Traders purchased machinery on the 01/01/2009 for R150 000. The machinery has a nil residual life. Depreciation is 25% per annum based on the cost method. Recoverable amount of the machinery is as follows based on the cost model:

31/12/2009 R100 000

31/12/2011 R50 000

Prepare the journal entries for Bee Traders from 2009 year to 2011 year. (Show all workings)

I would appreciate if you show me how you work out the amounts for journal entries :-)
