Question : The following table shows the mobile-addicted population of four different cities Hyderabad, Mumbai, Chennai, and Pune, and the ratio of males to females among them.
| City | Mobile addicted population | Male : Female |
| Hyderabad | 2,20,000 | 7 : 8 |
| Mumbai | 3,50,000 | 12 : 13 |
| Chennai | 2,00,000 | 11 : 9 |
| Pune | 1,50,000 | 9 : 11 |
Find the total number of addicted males in Chennai.
Option 1: 1,10,000
Option 2: 80,000
Option 3: 1,00,000
Option 4: 1,20,000
Correct Answer: 1,10,000
Solution :
The total mobile-addicted population in Chennai is 2,00,000 and the ratio of males to females is 11 : 9.
To find the number of addicted males, we first find the total parts in the ratio = 11 (for males) + 9 (for females) = 20 parts.
Each part is therefore equal to the total population divided by the total parts = $\frac{2,00,000}{20}$ = 10,000.
The number of addicted males in Chennai = 11 parts × 10,000 = 1,10,000
Hence, the correct answer is 1,10,000.
