the rate of depreciation= i = 6%
no.of years for which the mobile will be put to use =n= 4
value at the end of 4 years = A
P = value at the beginning = 20000
P(1-i)^n = A
20000(1-6/100)^4 = A
20000(1- 0.06)^4 = A
20000(0.84)^2 = A
20000(0.7056) = A
A = 9957.42
A= 9957.42= cost of the phone after 4 years
