Question
A group of five students has different height. Rohit is
shorter than Seema. Seema is shorter than Yaman. Diwakar is taller than only Hema. Who among the following is the tallest?Solution
Yaman > Seema > Rohit > Diwakar> Hema
A man rows upstream 36 km and downstream 51 km taking 3 hours each. Find the man’s speed in still water.    Â
When travelling downstream, a boat takes 5.25 hours to travel 252 km. If the speed of the stream is (3/8)th of downstream speed of the boat, ...
Ratio of speed of boat in downstream and speed of stream is 7:4, if speed of current is 8 km/hr, then find distance travelled (in km) upstream in 7 hours.
The speed of the stream is 12 km/h. Boat ‘A’ covers 120 km distance against the stream in 6 hours and boat ‘B’ covers 120 km distance against th...
A motorboat completes 36 km upstream and 96 km downstream together in 7 hours. If its speed in still water is 12 km/h more than the stream, determine th...
Ratio of downstream and upstream speed of a boat is 5:2. If the speed of stream is 3 km/h, find the distance travelled by boat in downstream in 2 hours.
A boat takes a total of 6 hours to go 24 km downstream and return 24 km upstream. The stream speed is 3 km/h. Find the speed of the boat in still water.
When travelling downstream, a boat takes 4.25 hours to travel 204 km. If the speed of the stream is (3/8)th of downstream speed of the boat, ...
The speed of current is 25 km/hr. If the speed of the boat in still water had been 5 km/hr more than the original speed, then it would take 4 hours to c...
Speed of a boat in still water is 3 times more than the speed of stream. If boat covers 135 km in downstream in 9 hours, then find the time taken by the...
