Machine that improves the efficiency of a cleaner cum grader by removing smaller and larger size impurities from the grain?
The paddy precleaner improves the efficiency of a cleaner cum grader by removing both smaller and larger size impurities from the grain.
Find the ratio between the speed of the boat and the speed of the stream.
The speed of the boat while travelling upstream is 24km/hr. The boat ...
A boat can travel 42 km downstream in 60 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 2. How much time will t...
The downstream speed of a boat is 8 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream ...
A boat can travel 36 km downstream in 40 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 4. How much time will t...
Boat ‘A’ can cover 120 km in still water in 10 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 4:5 and the sp...
A boy can swim a certain distance downstream in 3 hours and return in 7 hours. If the rate of stream is 4 kmph then what is the speed of boy in still wa...
Speed of boat in still water is 60% more than speed of current and total time takes by boat to cover certain distance going downstream and upstream is ...
The speed of a boat in still water is 9 km/hr and speed of current is 5 km/hr. If time taken to cover a certain distance upstream is 14 hours, then how ...
Boat ‘A’ covers 150 km in downstream in 15 hours. If the speed of stream is 2 km/hr then find the time taken by boat ‘A’ to cover 108 km in upst...
The speed of a boat in still water is 11 times the speed of the stream. If the difference between the upstream and downstream speed of the boats is 20 k...
