Question
As per the Global TB Report 2022, India notified over
21.4 lakh TB cases – _________ higher than 2020.Solution
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...
