Study the following table and answer question.
Number of students appeared in an examination from five cities:
| Cities | No. of Students (in thousands) | Ratio of students passed and failed |
| A | 54 | 5:04 |
| B | 126 | 4:03 |
| C | 84 | 10:11 |
| D | 96 | 9:07 |
| E | 132 | 6:05 |
The ratio of the total number of students passed in the examination from cities A and D to that of students failed from cities B and E?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 14 : 19
Total number of students passed in the examination from cities A and D = (5/9) × 54 = 30, (9/16) × 96 = 54
Students who failed from cities B and E = (3/7) × 126 = 54, (5/11) × 132 = 60
Required ratio = (30 + 54) : (54 + 60) = 84 : 114 = 14 : 19
