Correct Option: B
On the basis of above given details in question , we can say
From statement I , B − G = 40
| From statement II , G = 80% of B = | 4 | B | . |
| 5 |
∴ B : G = 5 : 4
Hence , the ratio of the number of boys and girls in a school is 5 : 4 .
The data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
