| Passed in Science but failed in Mathematics | 7 | 6 | 8 | 10 |
| Passed in both | 63 | 60 | 56 | 55 |
What is the ratio of numbers of students who failed in Science but passed in Mathematics of sections B and Section D together to the number of students of section A that passed in both subjects ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 3 : 9.
Explanation:
From the given table,
Number of students who failed in Science but passed in Mathematics of sections B and section D together = (12 + 15) = 27
The number of students of section A that passed in both subjects = 63
Now, the required ratio = 27 : 63 = 3 : 7.
Hence the ratio of numbers of students who failed in Science but passed in Mathematics of sections B and Section D together to the number of students of section A that passed in both subjects is 3 : 7.
