Answer 1

Answer:

population in 2003 = 54000 (amount)

let population in 2001 = P (principal)

rate = 5%

time = 2years

A. T. Q

Amount = Principal ( 1+Rate/100) n ( n is a power here)

54000 = P ( 1+5/100) 2 ( 2 is a power here)

54000 = P (21/20) 2

54000 = P × 21/20 × 21/20

54000 × 20/21 × 20/21 = P

P = 2400000/49

P = 48979.59 or 489.60 ( approx)
