Cells exist in two primary categories: prokaryotic cells (lacking a defined nucleus) and eukaryotic cells (containing membrane-enclosed organelles). These microscopic units carry out vital functions including division, growth, and homeostasis maintenance. In multicellular organisms, specialized cells organize into tissues, which further combine to form organs with specific functions.
A boat takes 1/12th time in moving a certain distance downstream than upstream. The ratio of the speed of the boat in still water and that of the curren...
Speed of a boat in still water is 5times more than the speed of stream. If boat covers 72 km in downstream in 6 hours, then find the time taken by the b...
Motor boat covers a certain distance downstream in a river in 20 hours. It covers the same distance upstream in 30 hours. If the speed of the water is 1...
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
Speed of a boat in still water to speed of boat in upstream is 12: 7. If the boat can travel 425 km in downstream in 5 hours, then find the time taken b...
A boatman takes 9 hours to cover 64 km downstream and 60 km upstream. If the ratio of his speed downstream to his speed upstream is 4:3, what is the spe...
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 ...
The ratio of speed of the boat and the speed of the current is 6:5. If the downstream speed of the boat is 44 km/hr. Then find how much distance will th...
