A television company purchased machinery for P130,000 on July 1, 1979. It is estimated to have a useful life of 10 years, a scrap value of P4,000, production of 400,000 units, and working hours of P130,000. The company used the machinery for P14,000 hours in 1979 and produced 35,000 units in 1979. Compute the depreciation for 1979 using A) working hours method B) output method.

Question: 

 A television company purchased machinery for P130,000 on July 1, 1979. It is estimated to have a useful life of 10 years, a scrap value of P4,000, production of 400,000 units, and working hours of P130,000. The company used the machinery for P14,000 hours in 1979 and produced 35,000 units in 1979. Compute the depreciation for 1979 using
A) working hours method
B) output method. 

 


PS: 
PLEASE SEE THE EXAMPLES AND THE REFERENCES BELOW, MAKE SURE TO FOLLOW THE FORMULAS BELOW

* Service-Output Method
In this method, it is assumed that the total depreciation that has taken place is directly
proportional to the quantity of the output of the property up to that time.
Let T = total units of output up to the end of life
Q₁ = total number of units of output during the nth year
depreciation per unit of output =
d=
(Co-C₂)

2. A television company purchased machinery for P100,000 on July 1, 1979. It is estimated that it will
have a useful life of 10 years; scrap value of P4,000, production of 400,000 units and working hours
of 120,000.
The company uses the machinery for 14,000 hours in 1979 and 18,000 hours in 1980. The machinery
produces 36,000 units in 1979 and 44,000 units in 1980. Compute the depreciation for 1980 using (a)
Straight line method (b) Working hours and (c) Output method
Solution:
Co = P100,000
CL = P4,000
T = 400,000 units H = 120,000 hours
