Stacks operates on the principle
ofSolution
The order in which elements come off a stack gives rise to its alternative name, LIFO (for last in, first out).
The speed of the boat in still water is 6 km/hr and the speed of the stream is 3 km/hr. A boat goes 108 km downstream with its usual speed but at the ti...
A man can row 32 km upstream and 60 km downstream in 8 hours. He can also row 40 km upstream and 48 km downstream in 6 hours. Find the speed of the man ...
A man can row 8 km/hr in still water. If the speed of the current is 2 km/hr, it takes 5 hours more in upstream than in the downstream for the same dist...
A boat goes 52 km in Downstream in 4 hours and takes 5 hours to complete a distance of 15 km in upstream. Find the speed of boat in still water.
Speed of current is equal to 25% of speed of boat in still water. If the boat takes 14 hours to cover 140 km in still water, then find the time taken by...
A boat moves at 40 km/hr downstream and 10 km/hr upstream. How long will it take to cover 150 km in still water?
The speed of the boat A and B in still water are in the ratio 15:13. The speed of the current for both boats is 16 km/hr. If the sum of time taken by bo...
