The value of a machine depreciates from Rs 32,768 to Rs 21,952 in three years. What is the rate % of depreciation?

• value of machine after n years=Initial Value(1-R/100)^n
  21952=32768(1-R/100)^3
  28=32(1-R/100)^3
  R=12.5%

• 32768:21952=512:343
  
  now take cube root on both sides
  
  8:7
  so the rate is 1/8*100=12.5%

• Let's R be the rate of depreciation
