A piece of equipment cost a certain factory 29000 rupees. If it depriciates it's value at 15% in the first year, 13.5% in the second year, 12% in third and so on. What will be the value of it at the end of ten years all percentages applying to original cost?

Answer 1

with
a = 0.15
d = -0.015
the sum of all the depreciations is
S10 = 10/2 (2*0.015 + 9*0.015) = 0.825
So it will be worth 29000 * 0.175 = 5075
