Answer:
given A = 976820 , P = 800000, n = 2, r= ?
976820 = 800000(1+r/100/)²
976820/800000 = (1+ r/100)²
97682/80000 = (1+r/100)²
48841/40000 = (1+r/100)²
(221/200)² = (1+r/100)²
as exponent are same on both sides, we can equate the bases
221/200 = 1+r/100
r/100 = 221/200 - 1
r/100 = 21/200
r = 21/200*100
r = 21/2
r = 10.5 %
growth rate is 10.5 %
