1)  

 The present value of an oil engine is 11547. What was the worth of the engine 5 before if the value depreciates at the rate of 6% every year.

Answer: 8474


SOLUTION 1 :

Given :

    A             =   11547

    r              =  6%

    n             =   5 years

Depreciation:

    A           =   P[1-(r÷100)]n

                 =   11547[1-(6÷100)]5

                 =   11547[1-0.06]5

                 =    11547 x (0.94)5

                 =   11547 x 0.7339040224

                 =   8474

 



2)  

 The present value of an oil engine is 12299. What was the worth of the engine 5 before if the value depreciates at the rate of 5% every year.

SOLUTION 1 :

Given :

    A             =   12299

    r              =  5%

    n             =   5 years

Depreciation:

    A           =   P[1-(r÷100)]n

                 =   12299[1-(5÷100)]5

                 =   12299[1-0.05]5

                 =    12299 x (0.95)5

                 =   12299 x 0.7737809375

                 =   9517
