"A Stack follows the Last-In-First-Out (LIFO) principle, meaning the last element added is the first to be removed. Examples include the call stack in programming. Common stack operations: push, pop. Stacks are used in undo operations. Can be implemented using arrays or linked lists."
The speed of a boat in calm water is 4 km/hr greater than the speed of the stream. The boat travels a distance of 280 km downstream and 200 km upstream ...
The ratio of the speed of boat in upstream to speed of boat in downstream is 7:9. If the boat can cover a total of 70 km upstream and 144 km downstream ...
A boat takes 24 hours to cover 'q' km in still water. While traveling downstream, it takes 16 hours to cover (q - 80) km. If the speed of the boat in st...
A man rows upstream 36 km and downstream 51 km taking 3 hours each. Find the man’s speed in still water.
The speed of the stream is 10 km/h. Boat ‘A’ covers 150 km distance against the stream in 6 hours and boat ‘B’ covers 108 km distance against th...
The speed of the stream is 15 km/h. Boat ‘A’ covers 100 km distance against the stream in 4 hours and boat ‘B’ covers 90 km distance against the...
A boy can swim a certain distance downstream in 3 hours and return in 8 hours. If the rate of stream is 5 kmph then what is the speed of boy in still wa...
A man can row 12 km/hr in still water. If the speed of the current is 3 km/hr, it takes 4 hours more in upstream than in the downstream for the same dis...
The speed of a boat in still water is 25 km/hr. If the boat covers 120 km in upstream in 12 hours, then find the time taken by the boat to travel 160 km...
A boat covers 13 km upstream in 52 min. If the speed of the current is 6 km / h, then in how much time will it cover 40 km downstream?
