Question 1 of 10
1. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following piechart and table carefully and answer the questions that follow
Time taken to cover the upstream distance in DAY 4 is 12 hours more than time taken to cover the Downstream distance in DAY 5. Total speed of still water in DAY 4 and DAY 5 is 11 km/hr. find the ratio of speedof still water in DAY 4 and DAY 5?
Correct
Answer : 1. 5: 6
Explanation
Distances upstream:
DAY 1 = 18/100 * 150 = 27 km, DAY 2= 12/100 * 150 = 18 km. DAY 3 = 39 km, DAY 4 = 45 km, DAY 5 = 21 km
Similarly Distances downstream:
DAY 1 = 27 km, DAY 2 = 45 km. DAY 3 = 18 km, DAY 4 = 36 km, DAY 5 = 54 kmLet speed of still water upstream in DAY 4 = x, then downstream in DAY 5 = (11x)
Now
45/(x2.5) – 54/[(11x)+3)] = 12
15/(x2.5) – 18/(14x) = 4
x = 5
So required ratio is 5: 6Incorrect
Answer : 1. 5: 6
Explanation
Distances upstream:
DAY 1 = 18/100 * 150 = 27 km, DAY 2= 12/100 * 150 = 18 km. DAY 3 = 39 km, DAY 4 = 45 km, DAY 5 = 21 km
Similarly Distances downstream:
DAY 1 = 27 km, DAY 2 = 45 km. DAY 3 = 18 km, DAY 4 = 36 km, DAY 5 = 54 kmLet speed of still water upstream in DAY 4 = x, then downstream in DAY 5 = (11x)
Now
45/(x2.5) – 54/[(11x)+3)] = 12
15/(x2.5) – 18/(14x) = 4
x = 5
So required ratio is 5: 6 
Question 2 of 10
2. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following piechart and table carefully and answer the questions that follow
In Day 3, Ratio of speed of boat in still water in going upstream to downstream is 4 : 5. The differencebetween time to cover upstream distance and downstream distance is 5 hours; find the total time taken to cover upstream distance and downstream distance?
Correct
Answer : 4. 8 hours
Explanation
In DAY 3
39/ (4x2) – 18/ (5x+2) = 5
x = 2 km/hr
39/(82) + 18/(10+2) = 8 hoursIncorrect
Answer : 4. 8 hours
Explanation
In DAY 3
39/ (4x2) – 18/ (5x+2) = 5
x = 2 km/hr
39/(82) + 18/(10+2) = 8 hours 
Question 3 of 10
3. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following piechart and table carefully and answer the questions that follow
In Day 2, Ratio of speed of boat in still water in going upstream to downstream is 3: 8. Also difference in speed of boat in still water in going upstream and downstream is 5 km/hr. If the total time taken by boat tocover upstream and downstream distance is 14 hours in Day 2, find the speed of stream?
Correct
Answer : 4. 1 Km/hr
Explanation
8x and 3x, Also 8x – 3x = 5
So x = 1, speeds are 8 and 3 km/hr
So for DAY 2
18/ (3b) + 45/ (8+b) = 14
b = 1 km/hrIncorrect
Answer : 4. 1 Km/hr
Explanation
8x and 3x, Also 8x – 3x = 5
So x = 1, speeds are 8 and 3 km/hr
So for DAY 2
18/ (3b) + 45/ (8+b) = 14
b = 1 km/hr 
Question 4 of 10
4. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following piechart and table carefully and answer the questions that follow
In DAY 1, the boat takes a total of 4 hrs 30 minutes to cover both upstream and downstream distance.Ratio of speed of boat in still water in going upstream to downstream is 4: 5. Find the speed of boat in stillwater while going downstream?
Correct
Answer : 5. 15 Km/hr
Explanation
Speeds – 4x and 5x
In DAY 1
27/ (4x3) + 27/(5x+3) = 9/2
Solve, x = 3
Downstream speed = 5x = 15 km/hrIncorrect
Answer : 5. 15 Km/hr
Explanation
Speeds – 4x and 5x
In DAY 1
27/ (4x3) + 27/(5x+3) = 9/2
Solve, x = 3
Downstream speed = 5x = 15 km/hr 
Question 5 of 10
5. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following piechart and table carefully and answer the questions that follow
Time taken to cover the upstream distance in DAY 5 is same as time taken to cover the downstream distance in DAY 4. Total speed of still water in DAY 4 and DAY 5 is 10 km/hr. find the ratio of speed of still water in DAY 4 and DAY 5?
Correct
Answer : 1. 7: 13
Explanation
Let speed of still water upstream in DAY 5 = x, then downstream in DAY 4 = (10x)
21/(x3) = 36/[(10x)+2.5]
x = 6.5
Ratio is 3.5: 6.5 = 7: 13Incorrect
Answer : 1. 7: 13
Explanation
Let speed of still water upstream in DAY 5 = x, then downstream in DAY 4 = (10x)
21/(x3) = 36/[(10x)+2.5]
x = 6.5
Ratio is 3.5: 6.5 = 7: 13
