Given A = 55125, Rate of interest r = 5%, time = 2 years(2010 - 2008).
We know that A = P(1 + r/100)^n
= > 55125 = P(1 + 5/100)^2
= > 55125 = P(21/20)^2
= > 55125 = P(441/400)
= > 55125 * 400 = 441 * P
= > 22050000 = 441P
= > P = 50000.
Therefore, the population of the village in year 2008 = 50000.
Hope this helps!
