Compound interest amount can be calculated using the formula : A = P(1+R/n)^(n*t)
As per your question,
R = 0.2
A1-A2=12500
P(1-0.2/n)^(n*t1) = P(1-0.2/n)^(n*t2)
To find : t1-t2
From above, P on either side can be cancelled out
i.e. (1-0.2/n)^(n*t1) = (1-0.2/n)^(n*t2)
Now, the equation can not be simplified further to get solution as there are 2 unknown variables :
n-number of times the interest is compounded and
t1-t2 : Difference in their years.

So the question is insufficient.

as Rs.12500 for 20% is 2500
so
we if we add 2500 every year
after 3 year +
we get 21600
