Direction: In each of the following questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer:
A and B finish 3/4th of a specific piece of work in 6 hours. How much time does A take to finish the work?
I. B finishes the work in 10 hours.
II. A and B together finish the work in 8 hours.
The question can be answered by using statement I alone but cannot be answered using the other statement alone.
The question can be answered by using statement II alone but cannot be answered using the other statement alone.
The question can be answered by using either of the statement alone.
The question can be answered using both of the statements together, but cannot be answered using either of the statement alone.
The question cannot be answered even by using both the statements together.
3/4th work in 6 hours. Total work can be completed in 8 hours.
From statement 1: 1/a + 1/b = 1/8 ⇒ 1/b = 1/10
Therefore, A finishes the work in 40 hours.
Statement 2 alone is not sufficient. Hence, option is 1.
