Though they were going through a string of successive victories on the field, sudden retirements of some senior players who usually played a pivotal role both on and off the field hurt their momentum. With the upcoming tour of Australia, coach Duncan Fletcher was in bit of a soup and so was the captain M.S. Dhoni. The recent decision of the board to promote Virat Kohli to be the subordinate to his captain offered relief. Hopefully this team will do well in the upcoming tour.

Answers ▼


Answer.1. 2; Replace ‘down with” “suffering from” usage of “down with” in this sentence is inappropriate.
You “suffer” an event or object, and “suffer from” a disease, condition, or symptom.
So, after you “suffer a stroke”, you might “suffer from amnesia”.
You can also “suffer a blow” or “suffer a loss”. You can even “suffer fools”, meaning “to put up with them”. When it’s used with a disease or medical state, it’s “suffer from”.
Answer.2. 5; The sentence is correct in its given form.
Answer.3. 2; Put the helpin verb “were” before “erected”, here Passive Voice of Past Indefinite Tense is used.
Answer.4. 5; The sentence is correct in its given form.
Answer.5. 1; It should be “new” at the place of “newly”.
Answer.6. 2; ‘Widely’ is logically apt in the given context. ‘Ample’ is an adjective while we require an adverb here, to modify the verb ‘recognised’ and hence is incorrect in the given context. Options (1), (4) and (5) are logically inappropriate in the given context.
Answer.7. 5; ‘Meet’ is the correct answer because one of the meanings of ‘meet’ is ‘to satisfy or fulfill’. All the other options are incorrect because ‘adhere’ means ‘to stick firmly to something’. ‘Gather’, ‘cover’ and ‘contact’ are logically inept in the given statement.
Answer.8. 3; ‘Seeks’ is the correct answer because it means ‘to try to obtain or achieve something’. Options (1) and (2) are incorrect because the blank needs to be filled with the present form of the verb while ‘sought’ and ‘wanted’ are past form of the verb ‘seek’ and ‘want’ respectively. Option (4) is incorrect because it renders the statement erroneous. The correct verb would have been ‘attempts’. Option (5) is incorrect because ‘determined’ should have been preceded by ‘is’ to make a grammatically correct statement.
Answer.9. 4; ‘Pace’ is the correct answer. The idiom ‘to keep pace’ means ‘to proceed at the same speed as someone or to stay at the same level as someone’. Options (1), (2) and (3) are logically inept in the given context. ‘Adequate’ is logically inept and it also does not go with the preposition ‘with’ right after the blank.
Answer.10. 1; ‘Access’ which means ‘the opportunity or right to use something’ is logically apt in the given context. Option (2) renders the statement grammatically erroneous. ‘Infiltration’ which means ‘to enter or make somebody enter a place or an organization secretly in order to get information that can be used against it’, ‘excess’ which means ‘more than is necessary’ and ‘rights’ are logically incorrect in the given context.
Answer.11. 5; ‘Emphasis’ which means ‘stress’ or ‘importance or attention given to something’ is logically apt in this context. ‘Intensity’ which means ‘the state or quality of being very strong’ and ‘place’ are logically inept the given context. ‘Aspiration’ which means ‘a strong desire to do something’ and ‘important’ render the statement logically and grammatically erroneous.
Answer.12. 3; ‘Provide’ is logically apt in this context.
Answer.13. 4; ‘Expected’ which means ‘to think or believe that something will happen’ is logically apt in this context. ‘Await’, ‘polled’ which means ‘to receive a particular number of votes in an election’, ‘leveled’ and ‘judged’ are logically inept in the given context.
Answer.14. 1; ‘Demand’ is logically apt in this context. Options (2), (3) and (5) are logically inept in the given context. Option (4) is incorrect because the transitive verb ‘expects’ needs to be followed by an object but the statement does not have one.
Answer.15. 5; From the latter part of the sentence which talks about the organization claiming to be unbiased, it can be clearly understood that ‘reject’ is the correct answer. Options (2), (3) and (4) are logically inept in the given context. Option (1) renders the statement logically and grammatically erroneous.

Quant Quiz ► Time Distance & Speed

Q1)-The ratio between the speed of a bus and a train is 15:27, respectively. Also, a car covered a distance of 720 km in 9 h. The speed of the bus is three-fourth of the speed of the car. How much distance will the train cover in 7 h?
760 km
756 km
740 km
None of these
Ans.- B 

Speed of car = 720/9 = 80 km/h
Speed of bus = 3/4 * 80 = 60 km/h
Speed of train = 27/15 * 60 = 108 km/h
Distance covered by train in 7 h = 108 * 7 = 756 km.


Q2)-A 320 m long train crosses a pole in 16 s. It stops five times of duration 18 min each. What time will it take in covering a distance of 576 km?
9 h
19/2 h
17/2 h
37/4 h
Ans.- B


Speed of train = 320 / 16 = 20 m/s = 20 * 18/5 = 72 km/h
Total time of stoppages = 5 * 18 = 90 min = 90/60 = 3/2 h
Time taken = 576/72 = 8 h
Total time taken = 8 + 3/2 = 19/2 h.


Q3)-Total time taken by a boat travelling from A to B and B to A, is 1 h 4 min. Speed of the boat in still water is 12 km/h and speed of the current is 3 km/h. What is the distance between A to B?
6 km
14 km
10 km
4 km
Ans.- A


Speed of upstream = (12 - 3) = 9 km/h
Speed of downstream = (12 + 3) = 15 km/h
Time = 1 h 4 min = 1 + 4/60 = 1 + 1/15 = 16/15
Let the distance between A to B is x km
=> x/9 + x/15 = 16/15
=> (5x + 3x)/45 = 16/15
=> 8x/45 = 16/15
=> x = 6 km.


Q4)-A motor starts with speed of 70 km/h with its speed increasing every 2 hours by 10 km/h. In how many hours will it cover 345 km?
9/4 h
9/2 h
4 h 5 min
Cannot be determined
Ans.- B


Distance covered in first 2 h = 70 * 2 = 140 km
Distance covered in next 2 h = 80 * 2 = 160 km
Distance cover in first 4 h = 160 + 140 = 300 km
Remaining distance = 345 – 300 = 45 km
Time taken = 45/90 = 1/2 h
Total time taken = 4 + 1/2 = 9/2 h


Q5)-A person travels from P to Q at speed of 40 km/h and returns to Q by increasing his speed by 150%. What is his average speed for both the trip?
36 km/h
45 km/h
48 km/h
50 km/h
Ans.- C


Speed of man from P to Q = (150 * 40)/100 = 60 km/h
Average speed = (2 * 40 * 60)/ (40 + 60) = 48 km/h


Q6)-A train crosses a 300 m long platform in 38 s while it crosses a single pole in 18 s. What is the speed of the train?
48 km/h
54 km/h
72 km/h
Cannot be determined
Ans.- B
Let the length of the train is x m
Speed of train = (x + 300)/38 m/s
When the train crosses a single pole, it covers its own length
Speed of train = x/18
=> (x + 300)/38 = x/18
=> 18x + 300*18 = 38x
=> 20x = 300 * 18
=> x = 15 * 18 = 270 km
Speed of train = 270/18 = 15 m/s = 15 * 18/5 = 54 km/h.


Q7)-A bus started its journey from Ramgarh and reached Devgarh in 44 min with its average speed of 50 km/h. If the average speed of the bus is increased by 5 km/h, how much time will it take to cover the same distance?
40 min
38 min
36 min
None of these
Ans.- A
Distance between Ramgarh to Devgarh = 50 * 44/60 = 110/3 km
New speed = 55 km/h
Required time = (110 /3 )/(55) = 2/3 hr = 40 min.


Q8)-The respective ratio between the speed of a car, a jeep and a tractor is 3:5:2. The speed of jeep is 250% of the speed of the tractor which covers 360 km in 12 h. what is the average speed of car and jeep together?
75 km/h
40 km/h
60 km/h
Cannot be determined
Ans.- C
Speed of tractor = 360/12 = 30 km/h
Speed of jeep = 30 * 250/100 = 75 km/h
Speed of car = 3/5 * 75 = 45 km/h
Average speed of car and jeep = (75 + 45)/2 = 60 km/h


Q9)-A man takes 6 h 35 min in walking to a certain place and riding back. He would have taken 2 h less by riding both ways. What would be the time he would take to walk both ways?
4 h 35 min
8 h 35 min
10 h
None of these
Ans.- B
Time taken in walking one way + riding other way = 6 h 35 min
Time taken in riding both ways = 4 h 35 min
Time taken in both ways = 13 h 10 min – 4 h 35 min = 8 h 35 min.


Q10)-A 255 m long train crosses a pole in 6 s. The same train crosses a man running in the same direction in 10 s. What will be the speed of the man?
15 m/s
17 m/s
18 m/s
14 m/s
Ans.- A
Let the speed of man is x m/s
Speed of train = 225/6 = 37.5 m/s
Relative speed when man is running in same direction : (37.5 - x) m/s
=> 225/(37.5 - x) = 10 s
=> 10x = 375 – 225
=> x = 15 m/s.
