1)  

 The present value of an oil engine is 11192. What was the worth of the engine 5 before if the value depreciates at the rate of 10% every year.

Answer: 6609


SOLUTION 1 :

Given :

    A             =   11192

    r              =  10%

    n             =   5 years

Depreciation:

    A           =   P[1-(r÷100)]n

                 =   11192[1-(10÷100)]5

                 =   11192[1-0.1]5

                 =    11192 x (0.9)5

                 =   11192 x 0.59049

                 =   6609

 



2)  

 The present value of an oil engine is 43307. What was the worth of the engine 2 before if the value depreciates at the rate of 3% every year.

Depreciation:

    A           =   P[1-(r÷100)]n

                 =   43307[1-(3÷100)]2

                 =   43307[1-0.03]2

                 =    43307 x (0.97)2

                 =   43307 x 0.9409

                 =   40748
