Question : The table shows the percentage of the total population of a city in different age groups. Study the table and answer the question.
| Age Group | Percentage |
| Upto 15 | 15.00 |
| 16-25 | 20.25 |
| 26-35 | 16.75 |
| 36-45 | 26.25 |
| 46-55 | 15.00 |
| 56-65 | 5.50 |
| 66 and above | 1.25 |
If there are 30 million people below 36 years, then the number of people (in millions) in the age group (56-65) is:
(considered up to two decimals)
Option 1: 1.16 million
Option 2: 3.17 million
Option 3: 1.87 million
Option 4: 2.17 million
Correct Answer: 3.17 million
Solution :
The total percentage of people below 36 years (up to 35 years) is the sum of the percentages of the age groups up to 15, 16-25, and 26-35.
⇒ 15.00 + 20.25 + 16.75 = 52%
Given that there are 30 million people below 36 years. Let the total population as P.
⇒ 30 = $\frac{52}{100}$ × P
⇒ P = 57.69 million
Now, the percentage of people in the age group 56-65 is 5.50%.
The number of people in this age group is given by:
= $\frac{5.50}{100}$ × P
= $\frac{5.50}{100}$ × 57.69 = 3.17 million
Hence, the correct answer is 3.17 million.
