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

1 pointsCategory: Quantitative Aptitude**Directions for question (1 – 5): Study the following table to answer the questions that follow. Some values are missing. Study the table carefully and answer the questions based on data in table and particular questions.**

Distance upstream = Distance downstream (if not stated)

Total time taken = Downstream time + Upstream time

**On 1st day, if difference between the time taken by the boat to go upstream and the time taken by the boat to go downstream is 20 hours, find the total time taken by the boat to go upstream and downstream.**CorrectAnswer :

**3. 60**

Explanation-

Given: 320/(a-4) – 320/(a+4) = 20

Solve, a = 12 km/hr = speed of boat

So total time = 320/(12-4) + 320/(12+4) = 40 + 20 = 60 hoursIncorrectAnswer :

**3. 60**

Explanation-

Given: 320/(a-4) – 320/(a+4) = 20

Solve, a = 12 km/hr = speed of boat

So total time = 320/(12-4) + 320/(12+4) = 40 + 20 = 60 hours - Question 2 of 10
##### 2. Question

1 pointsCategory: Quantitative Aptitude**Directions for question (1 – 5): Study the following table to answer the questions that follow. Some values are missing. Study the table carefully and answer the questions based on data in table and particular questions.**

Distance upstream = Distance downstream (if not stated)

Total time taken = Downstream time + Upstream time

**On 2nd day, if difference between the time taken by the boat to go upstream and the time taken by the boat to go downstream is 45 hours, find the total distance covered by the boat to go upstream and downstream. Downstream speed is 24 km/hr.**CorrectAnswer :

**4. 720**

Explanation-

Let downstream x and upstream y

x+y=75

x-y=45

solving x=15 and y=60, ‘APQ’ DOWN DISTANCE = UP DISTANCE

15*24(SPEED)=360*2=720IncorrectAnswer :

**4. 720**

Explanation-

Let downstream x and upstream y

x+y=75

x-y=45

solving x=15 and y=60, ‘APQ’ DOWN DISTANCE = UP DISTANCE

15*24(SPEED)=360*2=720 - Question 3 of 10
##### 3. Question

1 pointsCategory: Quantitative Aptitude**Directions for question (1 – 5): Study the following table to answer the questions that follow. Some values are missing. Study the table carefully and answer the questions based on data in table and particular questions.**

Distance upstream = Distance downstream (if not stated)

Total time taken = Downstream time + Upstream time

**On 3rd day, if the boat covered half distance upstream with usual speed and other half with double its speed, then it takes 33 3/4 hours less time than usual time to go upstream. Find the total time taken by the boat to go upstream and downstream.**CorrectAnswer :

**2. 108**

Explanation-

Let speed of boat = a km/hr

So 270/(a-6) – [135/(a-6) + 135/(2a-6)] = 33.75

270/(a-6) – 135/(a-6) – 135/(2a-6) = 33.75

135/(a-6) – 135/(2a-6) = 33.75

1/(a-6) – 1/(2a-6) = 1/4

Solve, a = 9 and 2

Speed of stream = 6 km/hr, so speed of boat = 9 km/hr (speed of boat remains greater than speed of stream) So total time = 270/(9-6) + 270/(9+6) = 90 + 18 = 108 hoursIncorrectAnswer :

**2. 108**

Explanation-

Let speed of boat = a km/hr

So 270/(a-6) – [135/(a-6) + 135/(2a-6)] = 33.75

270/(a-6) – 135/(a-6) – 135/(2a-6) = 33.75

135/(a-6) – 135/(2a-6) = 33.75

1/(a-6) – 1/(2a-6) = 1/4

Solve, a = 9 and 2

Speed of stream = 6 km/hr, so speed of boat = 9 km/hr (speed of boat remains greater than speed of stream) So total time = 270/(9-6) + 270/(9+6) = 90 + 18 = 108 hours - Question 4 of 10
##### 4. Question

1 pointsCategory: Quantitative Aptitude

Distance upstream = Distance downstream (if not stated)

Total time taken = Downstream time + Upstream time

**On 4th day, difference between time taken by the boat to cover ‘X’ km upstream and (X+120) km downstream is 26 hours. Had the boat covered same distance upstream as downstream, what would be the difference in time taken then?**CorrectAnswer :

**4. 56**

Explanation-

Downstream speed = 11+7 = 18 km/hr

Upstream speed = 11-7 = 4 km/hr

X/4 – (X+120)/18 = 26

Solve, X = 168 km = Upstream distance

Downstream distance = 168+120 = 288 km

Required time now = 288/4 – 288/18 = 56 hoursIncorrectAnswer :

**4. 56**

Explanation-

Downstream speed = 11+7 = 18 km/hr

Upstream speed = 11-7 = 4 km/hr

X/4 – (X+120)/18 = 26

Solve, X = 168 km = Upstream distance

Downstream distance = 168+120 = 288 km

Required time now = 288/4 – 288/18 = 56 hours - Question 5 of 10
##### 5. Question

1 pointsCategory: Quantitative Aptitude

Distance upstream = Distance downstream (if not stated)

Total time taken = Downstream time + Upstream time

**On 5th day, if ratio of speed of boat to speed of stream is 2 : 1, what is the difference between the time taken by the boat to go upstream and the time taken by the boat to go downstream?**CorrectAnswer :

**1. 36 hours**

Explanation-

Speeds = 2a, a

So 324/(2a+a) + 324/(2a-a) = 72

Solve, a = 6.So speed of stream is 6 km/hr and speed of boat is 12 km/hr

So difference in time = 324/(12-6) – 324/(12+6) = 54 – 18 = 36 hoursIncorrectAnswer :

**1. 36 hours**

Explanation-

Speeds = 2a, a

So 324/(2a+a) + 324/(2a-a) = 72

Solve, a = 6.So speed of stream is 6 km/hr and speed of boat is 12 km/hr

So difference in time = 324/(12-6) – 324/(12+6) = 54 – 18 = 36 hours - Question 6 of 10
