Total donation = R x r = 202500 Since the money received as donation is the same as the number of residents: r = R. Substituting this in the first equation, we get: R x R = 202500 R2 = 202500 R2 = (2 x 2) x (5 x 5) x (5 x 5) x (3 x 3)2 R = 2 x 5 x 5 x 3 x 3 = 450 So, the number of residents is 450.
