Statement of Cash FLow

We always need the cost paid for any non-current assets acquired. In 19.5 we are given the details of both the cost and the accumulated depreciation so we can find the cost just by looking at the cost balances. In 19.6 we are only given the net book values and so we have to sort out those balances (similar to the way I do in my lecture examples).

and sir I wanna ask something when we decrease the depreciation amount from the asset. like in lectures you have told us not to include current depreciation because it will be charged to depreciation expense to accumulated depreciation ac. but in 19.6 is been charged in the asset account only

In the SOFP's we are given the book values of the assets (we are not told the cost and accumulated depreciation amounts separately). The current years depreciation will reduce the book value of the assets.
