From the given graph,

No. of people between the age of 10 - 15 years = 1400

No. of people between the age of 20 - 25 years = 1200

No. of people between the age of 30 - 35 years = 1100

No. of people between the age of 40 - 45 years = 1000

No. of people between the age of 50 - 55 years = 900

No. of people between the age of 60 - 65 years = 800

No. of people between the age of 70 - 75 years = 300

The total Population of the town = 1400 + 1200 + 1100 + 1000 + 900 + 800 + 300 = 6700
