Question Details

A newly formed state government wants tobring more development in the state. Therefore, the  government proposed to launch various welfare programmes. Before bringing up any welfare programme, the state gtovernment intended to understand the population percentage of the state by age groups, so that the government could plan the welfare programmes accordingly. The state government found that the state’s 30 per cent of the population were children between the age group of 0-15. Next to child population, 17.75 per cent of the population were adolescents between the age group of 16 and 25. The early adult population, i.e., the age groups 26 to 35 were 17.25 per cent, 36 to 45 were 14.50 per cent, respectively. The population who are between the age group of 46 to 55 constitute 14.25 per cent and the elderly population of the state, i.e., 56 to 65 (5.12%) and 66 above (1.13%) was comparatively less than the other age groups. To get a better clarity, the state government concerned is seeking the answers to following questions:

Show Answer

Correct Answer :

Option C

31.50 million

Solution :

The correct option is 31.50 million.


Step-by-step Explanation:


1. Identify the relevant age groups below 36 years:

From the given data, the population percentages for the age groups below 36 years are:

• Age group 0 - 15 (Children): 30%
• Age group 16 - 25 (Adolescents): 17.75%
• Age group 26 - 35 (Early adults): 17.25%


2. Calculate the total percentage of population below 36 years:

Total percentage below 36 years = 30% + 17.75% + 17.25%

Total percentage below 36 years=65%


3. Calculate the total population of the state:

We are given that there are 400 million people below 36 years, which corresponds to 65% of the total population.

65% of Total Population=400 million

Total Population=40065×100 million

Total Population615.38 million


4. Calculate the population in the age group 56-65:

From the data, the population in the age group 56-65 is 5.12% of the total population.

Population (56-65)=5.12% of Total Population

Population (56-65)=5.12100×615.38 million

Population (56-65)=5.1265×400 million

Population (56-65)=204865 million31.5076 million


Therefore, the population in the age group 56-65 is approximately 31.50 million.
