 Hi and welcome to the session. I am Asha and I am going to help you with the following question which says, a manufacturer reckons that the value of a machine which cost him Rs 15,625 will depreciate each year by 20%. Find the estimated value at the end of 5 years. Let us now begin with the solution. And the cost price of the machine noted by P is equal to Rs 15,625. Rate of depreciation denoting it by capital R is equal to 20% per annum. And the time period at which we have to find the depreciated value is 5 years. And let us denote it by the estimated value end of 5 years P into 1 minus R upon 100 raised to the power values of the machine is 15625 into 1 minus rate is 20% 5 years. So this is further equal to 15625 into taking 100 is the way of 100 minus 20 upon 100 raised to the power 5 which is equal to 15625 into 80 upon 100 is 4 upon 5 raised to the power 5 which is further equal to 15625 into 1024 which is 4 raised to the power 5 upon 3125. And on cancelling we have 5 which is further equal to 5 into 1024 which is equal to 5120. Hence the depreciated value end of 5 years is equal to rupees 5120. So this completes the session. Take care and have a good day.
