Study the table below and use it to answer the question

 

 Cost Price (N)  Useful Life (Life)  Salvage value (N)  Annual depreciation (N)  Total depreciation
 20000  Y  5000  1000 annum  15000
 60000  10  18000  4200 annum  Z

The useful life represented by Y in the illustrated table is

A.

3 years

B.

4 years

C.

15 years

D.

20 years

Correct answer is C

Cost Price (N) = 20000
Salvage value (N) = 5000
Annual depreciation (N) = 1000
Total depreciation = 15000
The formula to calculate the useful life is:
Useful life = (Cost Price - Salvage value) / Annual depreciation
Now, let's plug in the values:
Useful life = (20000 - 5000) / 1000
Useful life = 15000 / 1000
Useful life = 15 years
Therefore, the useful life represented by Y in the table is 15 years.
