Question

Ram purchased an old Scooter for 8000 rupees if its cost after 2 years is 6480 rupees what is the rate of depreciation

Answer 1

let depreciation be x%
cost of old scooter 8000
depreciation= cost×rate×time
so, 8000×x%×2
total cost - depreciation=cost after depreciation
{8000-(8000×x%×2)=6480
8000-160x=6480
-160x=6480-8000
-x=-1520
x=9.5
so, depreciation rate= 9.5%
