Answer 1

Two years ago the population is,

A=P(1+r\100)^t

176400=P(1+5\100})^2

176400=P(1.1025)

P=1764001.1025

P=160000

Answer 2

Answer:

Total population 2 years ago was 160000.

Step-by-step explanation:

Given : Population of a town is 176400. If it increases at the rate of 5% per annum.

To find : What was Population 2 years ago ?

Solution :

Let P be the population, P=176400

r is the increasing rate, r=5%

t is the time (in years) t=2

Two years ago the population was,

A=P(1+r/100)^t

176400=P(1+5/100)^2

176400=P(1.1025)

P=176400/1.1025

P=160000

Total population 2 years ago was 160000.
