Study the following information carefully and answer the given questi...
To solve this problem, let's start by identifying the given information:
Speed of boat A in downstream = s + 21 km/hr
Speed of boat A in upstream = (5/3) * (s + 21) km/hr
Speed of boat B in still water = (4/7) * (s + 21) km/hr
Speed of boat C in still water = s - 14 km/hr
Now let's solve the questions step by step:
1. Speed of boat B in still water to speed of boat D in still water:
To find this ratio, we need to find the speed of boat D in still water. We know that boat C can catch boat D when they are traveling in the same direction. The distance between them is 50 km, and boat C takes 5 hours to catch boat D. Therefore, the speed of boat D in still water can be calculated as:
Speed of boat D in still water = Distance / Time
= 50 km / 5 hours
= 10 km/hr
Now, we can find the ratio of speed of boat B in still water to speed of boat D in still water:
Ratio = (4/7) * (s + 21) km/hr / 10 km/hr
= (2/5) * (s + 21) / 5
= 2/5 * (s + 21) / 5
= 2/25 * (s + 21)
So, the ratio of speed of boat B in still water to speed of boat D in still water is 2/25 * (s + 21).
2. Considering the given options:
a) 2:3
b) 5:3
c) 3:2
d) 4:3
e) None of these
Let's substitute the value of s and check which option matches the ratio we found:
If we substitute s = 3, the ratio becomes 2/25 * (3 + 21) = 2/25 * 24 = 48/25.
None of the given options match this ratio.
If we substitute s = 7, the ratio becomes 2/25 * (7 + 21) = 2/25 * 28 = 56/25.
None of the given options match this ratio.
If we substitute s = 14, the ratio becomes 2/25 * (14 + 21) = 2/25 * 35 = 70/25 = 14/5.
None of the given options match this ratio.
If we substitute s = 21, the ratio becomes 2/25 * (21 + 21) = 2/25 * 42 = 84/25.
None of the given options match this ratio.
If we substitute s = 28, the ratio becomes 2/25 * (28 + 21) = 2/25 * 49 = 98/25.
None of the given options match this ratio.
If we substitute s = 35, the ratio becomes 2/25 * (35 + 21) = 2/25 * 56 = 112/25.
None of the given options match this ratio.
If we substitute s = 42, the ratio becomes 2/25 * (42 + 21) =
Speed of boat A in downstream = s + 21 km/hr
Speed of boat A in upstream = (5/3) * (s + 21) km/hr
Speed of boat B in still water = (4/7) * (s + 21) km/hr
Speed of boat C in still water = s - 14 km/hr
Now let's solve the questions step by step:
1. Speed of boat B in still water to speed of boat D in still water:
To find this ratio, we need to find the speed of boat D in still water. We know that boat C can catch boat D when they are traveling in the same direction. The distance between them is 50 km, and boat C takes 5 hours to catch boat D. Therefore, the speed of boat D in still water can be calculated as:
Speed of boat D in still water = Distance / Time
= 50 km / 5 hours
= 10 km/hr
Now, we can find the ratio of speed of boat B in still water to speed of boat D in still water:
Ratio = (4/7) * (s + 21) km/hr / 10 km/hr
= (2/5) * (s + 21) / 5
= 2/5 * (s + 21) / 5
= 2/25 * (s + 21)
So, the ratio of speed of boat B in still water to speed of boat D in still water is 2/25 * (s + 21).
2. Considering the given options:
a) 2:3
b) 5:3
c) 3:2
d) 4:3
e) None of these
Let's substitute the value of s and check which option matches the ratio we found:
If we substitute s = 3, the ratio becomes 2/25 * (3 + 21) = 2/25 * 24 = 48/25.
None of the given options match this ratio.
If we substitute s = 7, the ratio becomes 2/25 * (7 + 21) = 2/25 * 28 = 56/25.
None of the given options match this ratio.
If we substitute s = 14, the ratio becomes 2/25 * (14 + 21) = 2/25 * 35 = 70/25 = 14/5.
None of the given options match this ratio.
If we substitute s = 21, the ratio becomes 2/25 * (21 + 21) = 2/25 * 42 = 84/25.
None of the given options match this ratio.
If we substitute s = 28, the ratio becomes 2/25 * (28 + 21) = 2/25 * 49 = 98/25.
None of the given options match this ratio.
If we substitute s = 35, the ratio becomes 2/25 * (35 + 21) = 2/25 * 56 = 112/25.
None of the given options match this ratio.
If we substitute s = 42, the ratio becomes 2/25 * (42 + 21) =

Study the following information carefully and answer the given questi...
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
According to question,
Speed of the boat B in still water = 45km/hr
Speed of the boat D in still water = 30km/hr
Required ratio = 45:30 = 3:2
