- Question 1 of 10
##### 1. Question

1 pointsCategory: Quantitative Aptitude**Q. (1-5) Study the following pie-chart 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?**CorrectAnswer :

**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 = (11-x)

Now

45/(x-2.5) – 54/[(11-x)+3)] = 12

15/(x-2.5) – 18/(14-x) = 4

x = 5

So required ratio is 5: 6IncorrectAnswer :

**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 = (11-x)

Now

45/(x-2.5) – 54/[(11-x)+3)] = 12

15/(x-2.5) – 18/(14-x) = 4

x = 5

So required ratio is 5: 6 - Question 2 of 10
##### 2. Question

1 pointsCategory: Quantitative Aptitude**Q. (1-5) Study the following pie-chart 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?**CorrectAnswer :

**4. 8 hours**

Explanation-

In DAY 3

39/ (4x-2) – 18/ (5x+2) = 5

x = 2 km/hr

39/(8-2) + 18/(10+2) = 8 hoursIncorrectAnswer :

**4. 8 hours**

Explanation-

In DAY 3

39/ (4x-2) – 18/ (5x+2) = 5

x = 2 km/hr

39/(8-2) + 18/(10+2) = 8 hours - Question 3 of 10
##### 3. Question

1 pointsCategory: Quantitative Aptitude**Q. (1-5) Study the following pie-chart 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?**CorrectAnswer :

**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/ (3-b) + 45/ (8+b) = 14

b = 1 km/hrIncorrectAnswer :

**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/ (3-b) + 45/ (8+b) = 14

b = 1 km/hr - Question 4 of 10
##### 4. Question

1 pointsCategory: Quantitative Aptitude**Q. (1-5) Study the following pie-chart 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?**CorrectAnswer :

**5. 15 Km/hr**

Explanation-

Speeds – 4x and 5x

In DAY 1

27/ (4x-3) + 27/(5x+3) = 9/2

Solve, x = 3

Downstream speed = 5x = 15 km/hrIncorrectAnswer :

**5. 15 Km/hr**

Explanation-

Speeds – 4x and 5x

In DAY 1

27/ (4x-3) + 27/(5x+3) = 9/2

Solve, x = 3

Downstream speed = 5x = 15 km/hr - Question 5 of 10
##### 5. Question

1 pointsCategory: Quantitative Aptitude**Q. (1-5) Study the following pie-chart 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?**CorrectAnswer :

**1. 7: 13**

Explanation-

Let speed of still water upstream in DAY 5 = x, then downstream in DAY 4 = (10-x)

21/(x-3) = 36/[(10-x)+2.5]

x = 6.5

Ratio is 3.5: 6.5 = 7: 13IncorrectAnswer :

**1. 7: 13**

Explanation-

Let speed of still water upstream in DAY 5 = x, then downstream in DAY 4 = (10-x)

21/(x-3) = 36/[(10-x)+2.5]

x = 6.5

Ratio is 3.5: 6.5 = 7: 13 - Question 6 of 10
