 Let us see another practical question. A machine which costs 30,000 had an estimated useful life of 5 years and an estimated solvage value of 10,000. So, in this case, you can see depreciable value is 30 minus 10, 20,000 and straight line depreciation is used. Give the entry in general journal from required for each of the following alternatives. There are two points that how the entry will be recorded in general. Now, the first one is the machine was sold for 19,500 after two years. So, you need to work out out of 30,000 with two years depreciation. Whatever depreciation comes to rest and then you compare with 19,500 and if there is profit or loss, we have to record. Similarly, sometimes we exchange an asset trading. The machine was trading in after three years, not two years after three years. So, there are three years depreciation could be taken into account. Another machine with a fair market value of 37,000 and trading allowance was 21,000. Trading allowance means the supplier of new machine said okay for this old machine, we give you 21,000 off. So, basically the cash you are going to pay is 16,000. Let us see. First, cost is 30, solvage value is 10. So, depreciable value is 20, useful life is 5 years. So, two years depreciation comes to 4,000 per year, 8,000. Net book value is 30 minus 28,22 and you are selling for 19,500. So, in this case, you are sustaining a loss. So, the entry will be debit cash, debit accumulated depreciation, two years depreciation and then loss of 2,500 and credit the machine by 30,000. Now, if there is an exchange, that is slightly difficult. Net book value after three years, after three years. So, three years depreciation is going to be 4,000 each year, 12,000. So, the carrying value is 18,000 and trading allowance given by the new supplier is 21,000. So, there is a gain on trading and cash we paid 16,000. So, see the entry. We debit new assets, the one which we are buying or other exchanging. Then the accumulated depreciation, which we have a credit balance in our account. So, we should debit that also and we also remove, de-recognize the old machine because it is handed over to the new supplier, which is 30,000. You also paid cash of 16,000 and since there is a gain on trade in 3,000, so we credit gain on trade in. Now, in some cases, you know you are buying a group of assets. So, that becomes a bit difficult that how to allocate the cost, total cost to those group of assets. So, there is a complication that we normally use the market value of those assets and accordingly we distribute the total amount according to the market value per a data basis. So, this is another issue of property, plant and equipment that when you are buying a group of assets, there is going to be a problem. Thank you very much.
