The census officer provided the data regarding changes in population of three major towns - A, B and C for three years. Population of town A was 180600 in third year and it increased by 5% and 7.5% in second and third year respectively. Population of town B increased by 25% in second year which was same as 150% of population of town A in first year. After taking population control measures, town B succeeded in controlling population as growth rate in third year was half of that of previous year. The area of town C is 1250 km2 and population density for second year was 250. Growth rate for town C was 11.11% and 10% for second and third year respectively.
Note : Population density = Total population / Total area. Growth rate is change in population over previous year for all towns and for all years.
In the third year, if 3/8th part of population of town A is not above 20 years, 33% of population of town B is of the age 20 years or less and 70% of population of town C is above 20 years, how much population of three towns is above 20 years in the third year?
  • a)
    530440
  • b)
    545400
  • c)
    534400
  • d)
    Cannot be determined

Considering solution to the first question, population above 20 years for
Town A = 180600 - [(180600 x 3)/8] = 112875
Town B = (100 - 33)% of 270000 = 180900
Town C = 70% of 343750 = 240625
Thus, required total = 112875 + 180900 + 240625 = 534400
Hence, option 3.

Population Calculation for Town A:
- Population of town A in the first year = x
- Population of town A in the second year = x + 5% of x
- Population of town A in the third year = 180600

Population Calculation for Town B:
- Population of town B in the second year = 150% of population of town A in the first year
- Population of town B in the third year = Population of town B in the second year * 0.5

Population Calculation for Town C:
- Population density of town C in the second year = 250
- Population of town C in the second year = Population density * area
- Population of town C in the third year = Population of town C in the second year * 1.111

Population above 20 years in the third year:
- Population above 20 years in town A = 5/8 * 180600
- Population above 20 years in town B = 67% of population of town B
- Population above 20 years in town C = 30% of population of town C
Therefore, calculating the above values and summing up the populations above 20 years in all three towns will give the answer. In this case, the total population above 20 years in the third year is 534400, which corresponds to option C.
