Boat & Stream is one of the most asked topics in the Quantitative Aptitude section of many banking/government/regulatory bodies exams like- RBI Grade B, RBI Assistant, SEBI Grade A, IBPS SO, IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, LIC AAO, SSC CGL, SSC CHSL, IFSCA Grade A, etc.

Boat and stream problems are a type of mathematical problem that involves calculating the speed of a boat relative to the speed of a stream or river. In these types of problems, the boat is assumed to be traveling upstream, downstream, or across the stream or river. The main objective of boat and stream problems is to calculate the speed of the boat or the speed of the stream or river, given the distance traveled, the time taken, and the relative speed of the boat and the stream.

There are various formulas used to solve boat and stream problems, depending on the given information. Some of the commonly used formulas include:

- Speed of boat in still water = (speed downstream + speed upstream) / 2
- Speed of stream or current = (speed downstream - speed upstream) / 2

By including boat and stream problems in competitive exams, the examiners can evaluate the candidate's ability to apply mathematical concepts to real-world situations. The problems also help to differentiate between candidates with similar academic backgrounds and identify those with exceptional problem-solving skills, making the selection process more efficient.
