P invested her capital for 12 months, Q for 9 months and R for 3 months. So, ratio of their capitals = (9000 × 12):(12000 × 9):(20000 × 3) ⇒ 108000 : 108000 : 60000 ⇒ 9 : 9 : 5 Therefore, R’s share = 6900 x (5/23) = Rs.1500
Find the total distance covered by boat in each upstream and downstream in 6 hours if the speed of boat in still water and speed of current is 18 km/h a...
A boat covers 12 km upstream and 20km downstream in 4 hours while it covers 20km upstream and 12 km downstream in 4*1/2 hours. What is the velocity of c...
A boat goes 52 km in upstream in 4 hours and takes 3 hours to complete a distance of 15 km in downstream. Find the speed of boat in still water.
Ratio of speed of boat in downstream and speed of stream is 5:2, if speed of current is 4 km/hr, then find distance travelled (in km) upstream in 6 hours.
A boat covers 144 km upstream and 192 km downstream in equal durations. If it takes 5 hours to travel 140 km in still water, determine the time the boat...
A motorboat in still water travels at a speed of 40 km/hr. It goes 45 km upstream in 2 hour 15 minutes. The time taken by it to cover the same distance ...
A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 5 hour to row to a place and come back, how far is the place?
A swimmer swims from point P against the current for 6 minutes and then swims back along the current for the next 6 minutes and reaches point Q. If the ...
A boat can travel 10 km more in downstream than that in upstream, in 5 hours while the difference between the time taken by the same boat to travel 250 ...
A boat has a speed of 52 km/h in still water. It takes 8 hours to travel from point B to point A downstream. The total distance between the two points ...
