The following table shows the percentage (%) distribution of number of sportspersons and number of male sportspersons participating in Asian Games from six different countries A-F. Total number of sportspersons who participated in the games is 1100 and the ratio of Male to Female among them is 15 ∶ 7. Based on the data in the table, answer the questions. Country-wise Distribution of Sportspersons Country Distribution (%) Sports persons Male Sportspersons A 21% 20% B 25% 22% C 15% 14% D 12% 12% E 9% 10%F 18% 22%
What is the ratio of the number of participants from Country D to the number of female participants from Country E?
11 ∶ 2
This problem requires us to analyze the distribution of sportspersons from different countries participating in the Asian Games based on the provided table and total numbers.
We need to find the ratio of the number of participants from Country D to the number of female participants from Country E.
The total number of sportspersons is 1100. The ratio of Male to Female is 15 ∶ 7. The total parts in the ratio are \(15 + 7 = 22\).
So, there are 750 male sportspersons and 350 female sportspersons in total.
According to the table, Country D accounts for 12% of the Total Sportspersons.
So, there are 132 participants from Country D.
According to the table, Country E accounts for 9% of the Total Sportspersons.
So, there are 99 total participants from Country E.
According to the table, Country E accounts for 10% of the Total Male Sportspersons.
So, there are 75 male participants from Country E.
The number of female participants from Country E is the difference between the total participants from Country E and the male participants from Country E.
So, there are 24 female participants from Country E.
We need to find the ratio of the number of participants from Country D to the number of female participants from Country E.
To simplify the ratio, we find the greatest common divisor (GCD) of 132 and 24. Both numbers are divisible by 12.
The simplified ratio is 11 ∶ 2.
| Description | Calculation | Result |
|---|---|---|
| Total Male Sportspersons | \(\frac{15}{22} \times 1100\) | 750 |
| Total Female Sportspersons | \(\frac{7}{22} \times 1100\) | 350 |
| Participants from Country D | 12% of 1100 | 132 |
| Total Participants from Country E | 9% of 1100 | 99 |
| Male Participants from Country E | 10% of 750 | 75 |
| Female Participants from Country E | 99 - 75 | 24 |
| Ratio (Country D : Female Country E) | 132 : 24 | 11 : 2 |
The ratio of the number of participants from Country D to the number of female participants from Country E is 11 ∶ 2.
| Concept | Explanation |
|---|---|
| Percentage Distribution | How a total quantity is divided into parts expressed as percentages. |
| Ratio | A comparison of two quantities. Can be simplified by dividing both parts by their GCD. |
| Calculating Parts from Ratio | If a total is divided in ratio A:B, the first part is \(\frac{A}{A+B} \times \text{Total}\) and the second is \(\frac{B}{A+B} \times \text{Total}\). |
