in prov for depn a/c
sept 30, depreciate the 2 vehicles at 25 % = credit 9000
apr 1, remove the depreciation of the vehicle being sold = debit 4000 (transfer to disposal) n balance is 5000 cr
sep30, depreeciate the remaining vehicle at 25% of its cost = 25% * 20000=5000, cr 5000, hence bal 10000 cr
remember he bought 2 cars, sold 1, still has 1 left that needs to be depreciated.
