| Direction: In the following questions, a question followed by two statements is given. You have to choose are out of the given five choices that answers the questions. |
| How much time did X take to reach the destination? |
| Statements: |
| I The ratio of the speed of X to that of Y is 4:7. |
| II Y takes 28 minutes to reach the destination. |
A) Statement II alone is sufficient to answer the question but statement I alone is not sufficient to answer the question.
B) Both statement I and II together are sufficient to answer the question, but neither statement I nor II alone is sufficient to answer the question.
C) Either statement alone is sufficient.
D) Statement I and II together are not sufficient to answer the question.
E) Statement I alone is sufficient to answer the questions, but statement II alone is not sufficient to answer the question.
Correct Answer: B
Solution :
From I and II. The ratio of the speeds =4:7 If\[x\]takes 4 minutes then y takes 7 minutes \[\therefore \]If y takes 2 8 minutes, then\[x\]takes \[=\frac{4}{7}\times 28=16\]minutes Hence both together are necessary to an question.
