Answer:
The total population of town after 2 years will be 84,640.
Step-by-step explanation:
Original Population = 64000
Growth rate per annum = 15%
Time = 2 years
Since we have to take the new population of town as the principal ,we can use the formula of CI.
Amount = P {1+ R/100}^T
= 64000 {1 + 15/100}^2
= 64000 {1 + 3/20}^2
LCM = 20
= 64000 {20+3 }²
20
= 64000 { 23 }²
20
= 64000 × 529
400
= 640 × 529
4
= 160 × 529
= 84,640
