City-wise Details of Population
Note: a < Age ≤ b means age belonging to group [a, b]
If the population of City-C and City-D in the age group of more than 60 years is equal to 24000 each, then what is the sum of the total population of City-C and City-D?
- A.
2.4 Lakh
- B.
2.8 Lakh
- C.
3.2 Lakh
- D.
4.8 Lakh
Show answer & explanation
Correct answer: B
From the table, for City-C, the percentage of population above 60 years is 15%. For City-D, it is 20%.
Given that the population above 60 years is 24,000 for both cities:
Total population of City-C = 24,000 / 15% = 24,000 / 0.15 = 160,000
Total population of City-D = 24,000 / 20% = 24,000 / 0.20 = 120,000
Sum of total populations = 160,000 + 120,000 = 280,000
Thus, the sum is 2.8 Lakh.
