Binary fission is an asexual mode of reproduction in which a cell splits into two daughter cells. This mode of reproduction is seen in Amoeba, Leishmania, and also in bacteria.
The speed of the stream is 15 km/h. Boat ‘A’ covers 140 km distance against the stream in 4 hours and boat ‘B’ covers 105 km distance against th...
A man can row at 36 km/hr in still water. In a stream which is flowing at 12 km/hr, it takes him 3 hrs to a place and back. How far is the place?

A boat running downstream covers a distance of 24 km in 3 hrs while it covers the same distance upstream in 6 hrs. Then speed of the boat in still water is
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...
The velocity of a vessel in calm waters is 4.5 times the speed of the current. If the disparity between the boat's speed when moving against the current...
A boat takes one-third time in moving a certain distance downstream than upstream. The ratio of the speed of the boat in still water and that of the cur...
(√3364+ √484) – √2916÷ √1296 × √36 ÷ √64 = ?
A person can swim at the rate of five kilometers per hour in still water. The time taken by him to swim a certain distance downstream is 3 times the tim...
A takes 3 hours more while swimming upstream than downstream. His speed in still water is 12 km/hr. The speed of stream is 4 km/hr. What is the distance?
