HCF = 5 LCM = 175 Ratio = 5:7 Let the numbers be 5x and 7x. Using the relation HCF × LCM = Product of the two numbers: 5 x 175 =5x × 7x 875 = 35x2 x2=875/35 =25 x=5 Larger number = 7x=7x5= 35.
The speed of a boat in still water is 32km/hr and the speed of the current is 8km/hr. It takes a total of 15hours to row to upstream from Point A to B a...
The speed of a boat downstream is 20% more than the speed of the boat in still water. If the boat can travel a distance of 288 km upstream in 18 hours, ...
The speed of a boat in still water is three times the speed of the boat upstream. If the boat takes 30 minutes to cover 27 km downstream, then find the ...
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...
A boat covers 13 km upstream in 52 min. If the speed of the current is 3 km / h, then in how much time will it cover 40 km downstream?
A man can go on a motor boat with a speed of 15 km/hour in still water, he goes to a certain distance upstream and come back to the starting point in a ...
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 7:4:2, respectively. If ...
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.
Two boats X and Y start towards each other from two places, 119 km apart. Speed of the boat X and Y in still water are 7 km/hr and 10 km/hr respectively...
If the sum of upstream and downstream speed is 32 km/hr and the speed of the current is 6 km/hr. Then find time taken to cover 44 km in downward?
