Answer 1

Answer:

176400

Step-by-step explanation:

The population in the year 2014=194481

Rate of increase in population per annum = 5%

Therefore the population in the year 2013 =x

x+(5x/100)=194481

105x=194481*100

x=185220

the population in the year 2012=y

y+(5y/100)=185220

105y=185220*100

y=176400.
