Let speed of boat A in upstream and downstream be ‘3x’ km/hr and ‘5x’ km/hr, respectively.
Speed of boat A in still water = (5x + 3x)/2 = ‘4x’ km/hr
So, speed of stream = (5x – 3x)/2 = ‘x’ km/hr
Speed of boat B in downstream = 360/6 = 60 km/hr
Speed of boat B in still water = (60 – x) km/hr
ATQ;
4x/(60 - x) = 4/3
12x = 240 – 4x
16x = 240
x = 15
So, speed of boatA in downstream = 5x = 5 × 15 = 75 km/hr
Speed of boat A in upstream = 3x = 3 × 15 = 45 km/hr
Speed of stream = x = 15 km/hr
Speed of boat A in still water = 4x = 4 × 15 = 60 km/hr
Since, speed of boat A in downstream = (s + 21) km/hr
So, s + 21 = 75
Or, s = 54
Speed of boat B in still water = 60 – 15 = 45 km/hr
Speed of boat B in upstream = 45 – 15 = 30 km/hr
Since, speed of boat C in still water = s – 14 = 54 – 14 = 40km/hr
Speed of boat C in upstream = 40 – 15 = 25 km/hr
Speed of boat C in downstream = 40 + 15 = 55km/hr
Let speed of boat D in still water is ‘p’km/hr
Since, boat C can catch boat D which is 50 km ahead of it in 5 hours, when both the boats are travelling in the same direction.
Relative speed of boat C w.r.t. boat D = (40 – p) km/hr
So, 50/(40 – p) = 5
40 – p = 10
p = 30
So, speed of boat D in still water = p = 30km/hr
Speed of boat D in upstream = 30 – 15 = 15km/hr
Speed of boat D in downstream = 30 + 15 = 45km/hr
Downstream speed of boat M = 1.20 × 75 = 90 km/hr
Upstream speed of boat M = 90 – 2 × 15 = 60 km/hr
Required time = 240/60 = 4 hours.

Study the following information carefully and answer the given questi...
Understanding Boat A's Speed
- Speed of Boat A in downstream = (s + 21) km/hr
- Given the ratio of downstream to upstream speed = 5:3
- Therefore, upstream speed of Boat A = (3/5) * (s + 21) km/hr
Calculating Speed of Boat B
- Boat B covers 360 km downstream in 6 hours.
- Speed of Boat B in downstream = 360 km / 6 hours = 60 km/hr
- Let speed of Boat A in still water = 4x and speed of Boat B in still water = 3x.
- The downstream speed of Boat B = speed of Boat B in still water + speed of stream.
- Speed of stream = 15 km/hr, hence:
- 3x + 15 = 60
- This leads to 3x = 45, thus x = 15.
- Therefore, speed of Boat A in still water = 4 * 15 = 60 km/hr.
Finding Speed of Boat A in Downstream and Upstream
- Speed of Boat A in downstream = 60 + 15 = 75 km/hr.
- Upstream speed of Boat A = 75 * (3/5) = 45 km/hr.
Calculating Speed of Boat M
- Downstream speed of Boat M = 120% of Boat A's downstream speed = 1.2 * 75 = 90 km/hr.
- Upstream speed of Boat M = 90 - 15 = 75 km/hr.
Calculating Time Taken by Boat M
- Distance to cover = 240 km.
- Time taken = Distance / Speed = 240 km / 75 km/hr = 3.2 hours.
Conclusion
- The calculated time is approximately 3.2 hours, which rounds to 4 hours, making the correct answer **option D** (4 hours).
- Speed of Boat A in downstream = (s + 21) km/hr
- Given the ratio of downstream to upstream speed = 5:3
- Therefore, upstream speed of Boat A = (3/5) * (s + 21) km/hr
Calculating Speed of Boat B
- Boat B covers 360 km downstream in 6 hours.
- Speed of Boat B in downstream = 360 km / 6 hours = 60 km/hr
- Let speed of Boat A in still water = 4x and speed of Boat B in still water = 3x.
- The downstream speed of Boat B = speed of Boat B in still water + speed of stream.
- Speed of stream = 15 km/hr, hence:
- 3x + 15 = 60
- This leads to 3x = 45, thus x = 15.
- Therefore, speed of Boat A in still water = 4 * 15 = 60 km/hr.
Finding Speed of Boat A in Downstream and Upstream
- Speed of Boat A in downstream = 60 + 15 = 75 km/hr.
- Upstream speed of Boat A = 75 * (3/5) = 45 km/hr.
Calculating Speed of Boat M
- Downstream speed of Boat M = 120% of Boat A's downstream speed = 1.2 * 75 = 90 km/hr.
- Upstream speed of Boat M = 90 - 15 = 75 km/hr.
Calculating Time Taken by Boat M
- Distance to cover = 240 km.
- Time taken = Distance / Speed = 240 km / 75 km/hr = 3.2 hours.
Conclusion
- The calculated time is approximately 3.2 hours, which rounds to 4 hours, making the correct answer **option D** (4 hours).
