Question

the value of a car what 150000 is depreciating 10% per annum in how many years will its value be reduced to 109350​

Answer 1

10% of 150000 = 15000 will be depreciated in 1st year
Now amount left=150000-15000=135000
2 nd yr 10% of 135000 =13500 depriciates from 135000
So amount left = 135000-13500=121500
In 3rd yr 10% of 121500 =12150 so amount left after 3 rd yr=121500-12150=109350
So it takes 3 years
Hope it helps
