please solve this question

I will mark brainlist

Answer 1

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!
