f.5 accounting

extract from B/S as at 30 June 2005

machinery at cost 156000
provision for depreciation on machinery 60000

Additional information:
1) one machine was taken away as scrap but no cash was received. it cost $1600 and was depreciated by $1200.

唔明做d咩?? P/L depreciation個數係幾多?
入balance sheet個數又點計?
