Let the principal, rate and time be Rs P, r and t years.

Also, let the initial principal be Po.  Integrating both sides, we have ∫dt

log|P| = t + c……(1)

Now, at t = 0, P = Po

log| Po | = 0 + c

c = log| Po |……(2)

Putting the value of c in equation (1) we have,

log|P| = t + log|Po|

log|P| – log|Po| = t

(log |P| – log|Po|) = t [ ]

log ( = t ……(3)

Now, t = 1 year, r = 8%

log ( = ×1

log ( = 0.08   (Given: = 1.0833) Percentage increase = 0.0833×100 = 8.33%
