Question

A machine costing rupees 30000 is depreciated at 20% by diminishing balance method. How long will it take to reduce it's value to rupees 15000​

Answer 1

Step-by-step explanation:

p= 30000

r= 20%

pd.= 15000

t= ?

pd.= p (1-r/100)^t

15000= 30000 (1-20/100)^t

15000/30000 =(1-0.2)^t

0.5 =(0.8)^t
