Answer :
Step-by-step explanation:
To find the rate of depreciation and the original cost of the machine, we can use the information provided about the depreciation amounts during the second and third years.
Let's start by calculating the rate of depreciation:
(i) Rate of depreciation = Depreciation amount / Original cost of the machine
Given:
Depreciation during the second year = Rs.644
Depreciation during the third year = Rs.592.48
Now, we can calculate the rate of depreciation using the formula above.
Once we have the rate of depreciation, we can move on to find the original cost of the machine. Let's calculate these values step by step!
