let the sum = p
rate of interest = r %
A1 = 13230
A2 = 13891.50
rate of interest in half yearly will be = r/2 % (conversion period)
as the amount is invested for 1 year and 1.5 years
so conversion are 2 and 3
A = P(1 + r/100)^n
13230 = P(1 + r/200)^2 …..........(i)
13891.5 = P(1 + r/200)^3 …...........(ii)
divide (ii) by (i)
1 + r/200 = 1.05
r/200 = .05
r = 10 %
put the value of r in (i) or (ii) –
P = 12000 rupees
