Quantitative Aptitude(IBPS PO) Data Sufficiency

The question consists of three statements numbered “I”, "II", and “III” given below it. You have to decide whether the data provided in the statements are sufficient to answer the question or not and choose the correct option accordingly. Two boats A and B are rowing in two different rivers M and N respectively. Find the distance covered by Boat B in 12 hours traveling downstream.

Statement I: Boat B can cover 96km upstream in 4 hours. Two boats A and B can cover 360km downstream in 6 hours.

Statement II: Speed of Streams in both the rivers is 7 hours

Statement III: The distance covered by Boat B in Y hours downstream is 150km more than the distance covered by Boat B in (Y + 5) traveling upstream.

Explanation:

- Statement I: Boat B covers 96 km upstream in 4 hours, and both boats together cover 360 km downstream in 6 hours. From this, we learn Boat B's upstream speed = 24 km/h. We cannot find Boat B's downstream speed from this alone.

- Statement II: States the speed of streams as 7 km/h. Alone or even combined with I, it does not provide Boat B's downstream speed.

- Statement III: Discusses a relationship between distances covered by Boat B but doesn't specify specific distances or speeds. Alone or even combined with other statements, it does not give exact measures to find 12-hour downstream distance.

- Option 1 to 4: Each option, alone or in combinations, lacks sufficient information to deduce Boat B’s downstream speed.

- Option 5: None of the statements, alone or together, give exact downstream speed for Boat B.

Correct Answer: Option 5 - None of these
