In a bank principal increases at the rate of 5% per year. An amount of ` 1000 is deposited with this bank, how much will it worth after 10 years (e0.5 = 1.648).
Let p, and t represent the principal, time respectively.
It is the given that the principal increases continuously at the rate of 5% per year.
=
=
Integrating both sides, we get:
=
=
= p = .....-(i)
It is given that when t = 0, p = 1000
= 1000 = ec .....--(2)
Now,
Putting t = 10,we get
=
=
= p = 1000 x 1.648
= p = 1648
