Direction: Each question below is followed by two statements I and II. You have to determine whether the data given in the statement is sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose the best possible answer.
X, Y and Z together can do a piece of work in 19 days. Find in how many days Z alone can complete the work.
Statement I. X and Y together can complete the work in 28.5 days and Y and Z together can complete the work in 38 days.
Statement II. Y takes 29 days to complete the work alone.
1
The statement I alone is sufficient to answer the question but, statement II alone is not sufficient.
2
The statement II alone is sufficient to answer the question but, statement I alone is not sufficient.
3
Both the statements I and II together are needed to answer the question.
4
Either statement I alone or statement II alone is sufficient to answer the question.
5
Neither statement I nor statement II is sufficient to answer the question.
