1.The following data shows the variation in population of a town from 1950 to 2000. Find out the population of the town in the year 2025 and 2030 by using arithmetic and geometric increase methods.

Year	1950	1960	1970	1980	1990	2000
Population	53050	62070	80350	95066	99087	12090

2. Estimate the population of a town for design year 2030 AD by any three methods and calculate the design quantity of water in liters/day. The census data are as follows:Also, consider losses and wastage.

Year(AD)	1970	1980	1990	2000
Population	40,000	45,000	55,000	62,000

3.Determine the population of the town in the year 2021 and 2026 by
