Quantitative Aptitude: Time, Speed and Distance Set 21

  1. Neelaksh is standing on a bridge which is 180 m long. He finds that a train crosses the bridge in 20 seconds but himself in 8 seconds. Find the speed of the train?
    54 kmph
    42 kmph
    45 kmph
    51 kmph
    None of these
    Option A
    A/8 =( A + 180) / 20 = 20A = 8(A + 180) = A = 120.
    Length of the train = 120 m.
    Speed of the train = [120/8]m/sec
    =[120/8] * 18/5kmph = 54 kmph.

     


  2. Two express are running at 40 km/hr and 20 km/hr respectively in same direction. The fast express completely passes a women sitting in slower express in 5 seconds. What is the length of fast express?
    35
    27 (7/9)
    32(1/7)
    25
    None of these
    Option B
    Relative speed = (40-20) km/hr = [20 x 5/18] m/sec = [50/9] m/sec.
    Length of faster train=[50/9 x 5] m = 250/9 m

     


  3. Excluding stoppages, the speed of a train is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the train stop per hour?
    15 minutes
    7 minutes
    12 minutes
    10 minutes
    None of these
    Option D
    Time taken to cover 9 km = (9/54 x 60) min = 10 minutes

     


  4. A train starts with speed of 70 km/hr with its speed increasing every two hours by 10 kmph. In how many hours will it cover 345 kms?
    1 hours
    4.5 hours
    5 hours
    7.5 hours
    None of these
    Option B
    Distance covered in first 2 hours= (70 x 2) km
    Distance covered in next 2 hours= (80 x 2) km
    Remaining distance = 345 – (140 + 160) = 45 km.
    Speed in the 5th hour = 90 km/hr
    Time taken to cover 45 km = as speed is 90km/hr means it covers 90 km in 1 hour
    Total time taken = 2 + 2 +1/2=4 (1/2)hrs

     


  5. Ramesh travelled from X to Y at a speed of 40 kmph and returns by increasing his speed by 50%. What is his average speed for both the trips?
    42 kmph
    48 kmph
    41 kmph
    40 kmph
    None of these
    Option B
    Average speed = [2 x 40 x 60] / [40 + 6]km/hr =4800/100km/hr =48 km/hr.

     


  6. Three buses are running from a place P to another place Q. Their speeds are in the ratio of 4 : 3 : 5. The time ratio to reach Q by buses will be which of the following?
    15:20:12
    10:12:15
    16:18:20
    Cannot be determined
    None of these
    Option A
    Ratio of times taken [t=d/s or t indirectly proportional to s when distance is same]= (1/4) : (1/3) : (1/5) = 15 : 20 : 12

     


  7. The distance between two states P and Q is 330 km. A bus starts from P at 8AM. and travels towards Q at 60 km/hr. Another bus starts from Q at 9AM. and travels towards P at 75 km/hr. At what time do they meet?
    11:15 AM
    11 AM
    10:30 AM
    10:15 AM
    None of these
    Option B
    Suppose they meet t hrs after 8AM
    Then,(Distance moved by first in t hrs) + [Distance moved by second in (t-1) hrs] = 330
    60t + 75(t–1) = 330 km
    t = 3
    So, they meet at (8 + 3), i.e. 11AM

     


  8. Two buses of equal length are running on parallel lines in same direction at 46 km/hr and 36 km/hr. The faster bus passes the slower bus in 36 seconds. The length of each bus is which of the following?
    50
    45
    55
    60
    None of these
    Option A
    Relative speed= L/T
    (46-36) * 5/18 = [L + L ] / 36
    10 * (5/18) *36 * (1/2)= L
    L=50 m

     


  9. A bus 125 m long passes a girl, running at 5 kmph in the same direction in which the bus is going, in 10 seconds. The speed of the bus is which of the following?

    7:8
    3:5
    1:2
    4:3
    None of these
    Option D
    (P’s speed) : (Q’s speed) = square root of Q : square-root of P =square-root of 16 : square-root of 9 = 4 : 3

  5. Directions(5-7): In the given question, a sentence is divided into five parts out of which the last part is correct. Out of the remaining four, there is an error in one of the parts. Choose the part which has an error. If there is no error, mark E i.e. 'All are correct' as the answer.

  6. In 1766, the German philosopher (A)/ Immanuel Kant declared that people (B)/ who claim to see spirits, such as (C)/ his contemporary, the Swedish (D)/ scientist Emanuel Swedenborg, are mad.
    A
    B
    C
    D
    All are correct
    Option E

     


  7. A yawn, or an oscitation, is technically (A)/ a reflexive action for which (B)/ one simultaneously breath (C)/ in, stretch their eardrums (D)/ and then exhales the breath.
    A
    B
    C
    D
    All are correct
    Option A
    Part B: Replace 'for' with 'in'. The sentence attempts to imply what is involved when somebody yawns.
    Part C: Breath is a noun. There should be a third person present form of the verb (breathes) to agree with the noun (one).
    Part D: The verb 'stretch' is for the noun 'action'. Action is a singular noun, so a singular verb will follow. So, it will be 'stretches'.

     


  8. China appreciates Nepal firm adherence (A)/ from the one-China policy, respects Nepal's independent (B)/ choice of social system and development (C)/ path, and support Nepal in safeguarding its national (D)/ independence, sovereignty and legitimate rights and interests, he said.
    A
    B
    C
    D
    All are correct
    Option C
    The error in A is the incorrect use of ‘Nepal’ and needs to be replaced with ‘Nepal’s’ to make the sentence grammatically and contextually correct. This is because the possession is being made and in order to show possession apostrophe (‘s) is used.
    The error in part B of the sentence is the incorrect use of ‘from’ and needs to be replaced with ‘to’ to make the sentence grammatically and contextually correct. This is because; ‘to’ suggest the noun to which the previously mentioned noun is compiled. ‘Adherence’ is the fact of someone behaving exactly according to rules, beliefs, etc., thus, ‘to’ should be used in the case and not ‘from’.
    The error in D is ‘support’ which must be replaced with ‘supports’. This is because to the noun ‘China’ is a single noun and thus should be followed by a singular verb i.e. ‘supports’, to describe that China supports Nepal in safeguarding its national independence, sovereignty and legitimate rights and interests.

     


  9. Directions(8-10): Which of the following phrases (i), (ii), and (iii) given below each sentence should replace the phrase in brackets to make the sentence grammatically correct? Choose the best option among the five given alternatives that reflect the correct use of phrase in the context of a grammatically correct sentence. If the sentence is correct as it is, mark (E) i.e., "No correction required" as the answer.

  10. India's Mars Orbiter, (which is poised to slip into orbit about) the red planet on Wednesday, is the world's lowest-budget mission to the red planet.
    i. which is poised to slip into orbit around
    ii. which is about to slip into orbit about
    iii. which is posed to slip into orbit around
    Only i
    Only ii
    Only iii
    ii and iii
    No correction required
    Option A
    'About' is used in situations where approximations are being made. It can be related to time or space. But in the given sentence, we are talking about a scientific endeavour that involves millions of calculations and relies on their accuracy. There is no place for approximation here. So, the Orbital has to be in a fixed orbit around mars.
    To pose means to sit or stand in a particular position in order to be painted, drawn or photographed. To poise means to be or keep something balanced or suspended. The Orbital has to be in perfect position in order to enter the orbit around mars.

     


  11. The business looks at this new country and decides to move there because, from their standpoint, (they can make costs and be more efficient).

    i. it would benefit their CEO's personal life
    ii. they can save costs and be more efficient
    iii. but to be cost efficient and tax exemptions.
    Only i
    Only ii
    Only iii
    ii and iii
    No correction required
    Option B
    The highlighted part is wrong because we can be more efficient and save money, not make them. 'Make' is not the suitable verb in this case.
    Option i is wrong, as no company would change their base country for such a reason, or at least not openly.
    Option iii uses 'but' which is used to state contradictions. But the phrase following 'but' doesn’t contradict anything from the given statement.

     


  12. The company should insure its workers because (if uninsured workers end up into the ER), the burden falls on society, not the company.
    i. when these uninsured workers end in ER
    ii. when the uninsured workers fall ill
    iii. if these uninsured workers suffer injury
    Only i
    Only ii
    Only iii
    ii and iii
    No correction required
    Option D
    We use 'into' to talk about the movement of something, usually with a verb that expresses movement (e.g. go,come). It shows where something is or was going. But in the given sentence, there is no such movement. The sentence is stating the position of the workers. In such cases, we use the preposition 'in'.
    The verb 'end' is a synonym of the verb 'finish'. The verb 'end' is used more often as an intransitive verb. The phrasal verb "end up" communicates, not termination, but an eventual circumstance. Here, the workers may have to visit the ER if/when they are injured or sick.

Mixed English Questions for Mains Exam — Set 331

Directions(1-5): In the questions, one sentence is given and four words are donated by (A), (B), (C) and (D). You have to decide which of the following is inappropriate in the context. If all the words are appropriate in the context, mark ‘All are correct’ as your answer.

  1. A regulatory agency(A) that is at the government’s mercy to run its finance(B) and administrative(C) operations cannot be expected(D) to be independent.
    A
    B
    C
    D
    All are correct
    Option B
    The word ‘finance' has been wrongly used here. Note that the word ‘finance' is a noun and we need an adjective to be parallel to the adjective ‘administrative’, both modifying the noun ‘operations’. Thus, ‘financial' should replace ‘finance' to make the statement meaningful. Hence, option B is the correct answer.

     


  2. It is assumed(A) that facial(B) recognition will introduce efficiency(C) and speed in forcing(D) law and order.
    A
    B
    C
    D
    All are correct.
    Option D
    The error is in part D as the word ‘forcing’ is wrongly used here. According to the context, facial expression will introduce efficiency in imposing law and order. The word similar to impose would be ‘enforcing’ which means something you do to ensure a rule or a law is followed and ‘forcing’ means something you do to make a person do something. Thus, ‘enforcing’ should be used in place of ‘forcing’. Hence option D is the correct answer.

     


  3. Minimum wage and collective bargaining(A) systems are labour market institutions(B) that also excerpt(C) an influence on the level and distribution(D) of wages.
    A
    B
    C
    D
    All are correct
    Option C
    The word ‘excerpt’ used in option C is not appropriate according to the context. Excerpt means a short extract from a film or a piece of writing or music and this word does not make sense. ‘Exert’ should be replaced with ‘excerpt’ as it makes the sentence contextually correct. ‘Exert’ means ‘to apply’. Hence, option C is the correct answer.

     


  4. The lack of financial autonomy(A) can affect SEBI’s plans to improve the quality(B) of its operations by vesting(C) in new technologies and other requirements to upgrade(D) market infrastructure.
    A
    B
    C
    D
    All are correct
    Option C
    The error is in part C as the word ‘vesting’ is wrongly used here. According to the context, the lack of financial autonomy would affect SEBI’s plans to invest in new technologies. Vesting is a legal term to give or earn a right to a present or a future payment, asset or benefit. Here, ‘investing’ which means “put (money) into financial schemes, shares, property, or a commercial venture with the expectation of achieving a profit" should be used in place of ‘vesting’. Hence, option C is the correct answer.

     


  5. Under the ABC rules, holiness(A) dogs must be maintained(B) in the place where they were found(C), regardless of whether they are abandoned(D)or lost.
    A
    B
    C
    D
    All are correct
    Option A
    The context explains that there are certain type of dogs which when found on streets must be maintained in a place according to ABC rules. The word ‘holiness’ is contextually incorrect, for which an appropriate choice is “homeless”. Therefore the error is in option A and is the correct answer.

     


  6. Directions(6-10): In the given question, four words are numbered A, B, C, and D. You have to decide which of the following is inappropriate in the context. If all the words are appropriate in the context then mark ‘All correct’ as your answer.

  7. The US emerged(A) everyone to see that growth and development(B) for one country could benefit(C) all countries through increased trade and investment(D).
    A
    B
    C
    D
    All are correct
    Option A
    The error is in word at A, which means the word ‘emerged’ has been wrongly used here. It should be replaced with ‘urged’, which means to earnestly persuade someone to do something.

     


  8. The skin cancer, cataracts, and other dexterous(A) effects will continue, and the people exposed(B) to ultra violet radiation will suffer its consequences(C) even after the ozone layer is healed(D) to a great extent.
    A
    B
    C
    D
    All are correct
    Option A
    Dextrous means showing or having skill. The sentence is talking about the ill effects of being exposed to ultra violet rays. Hence, the word Dextrous doesn’t fit in the context. A word that will tell us about the nature of effects of the UV rays. We can use words like detrimental or deleterious. Deleterious means something that causes harm or damage.

     


  9. A landscape restoration(A) approach would require the ministry to shift its focus(B) to the recognition(C) of the importance of ecosystem services like biodiversity conservative(D) and watershed management.
    A
    B
    C
    D
    All are correct
    Option D
    The sentence is conveying the idea that the ministry is must shift its focus to the recognition of better practices for landscape restoration. The word conservative refers to a traditionalist. We need a word that would mean the protection of biodiversity. Hence, conservation would be the best.

     


  10. There is no likelihood(A), nor should the government contemplate(B), of allowing easy/concessional tariff(C) access to foreign dairy products under the Regional Comprehensive Economic Partnership or any other bilateral or multilateral agreement(D).
    A
    B
    C
    D

Quantitative Aptitude: Boats and Streams Questions Set 7

  1. A boat running downstream covers a distance of 36 km in 4 hrs and for covering the same distance upstream it takes 9 hrs. What is the speed of the stream?
    2.5 km/hr
    3 km/hr
    4.5 km/hr
    5 km/hr
    None of these
    Option A
    Downstream speed = 36/4 = 9 km/hr
    Upstream speed = 36/9 = 4 km/hr
    So, speed of stream = 1/2*(9-4)=2.5 km/hr

     


  2. It takes 5 times as long to row a distance against the stream as to row the same distance in favor of stream. What is the ratio of the speed of the boat in still water to that of stream?
    7:5
    3:2
    2:5
    1:6
    None of these
    Option B
    B = [t1u + t1d] / [t1u – t1d] * R
    So,B =[5x + x] / [5x- x] * R
    So B/R = 6/4 = 3:2

     


  3. Rakesh rows to a place 40 km distant and back in total of 18 hours. He finds that he can row 5 km with the stream in same time as 4 km against the stream. What is the speed of boat in still water?
    3.0 km/hr
    4.5 km/hr
    4.5 km/hr
    6 km/hr
    5 km/hr
    Option C
    Suppose he moves 5 km downstream in t hours
    Then, downstream speed a= 5/t km/hr
    Speed upstream speed b = 4/t km/hr
    40 / (5 /t) + 40 / (4/t) = 18
    8t + 10t = 18
    t = 1
    a = 5 km/hr, b = 4 km/hr
    speed of boat = ½ (5 + 4 ) =4.5 km/hr

     


  4. If Neelaksh can swim downstream at 6 kmph and upstream at 2 kmph.What is his speed in still water ?
    9 km/hr
    7 km/hr
    5 km/hr
    4 km/hr
    None of these
    Option D
    Speed downstream a = 6 kmph
    Speed upstream b = 2kmph
    Speed in still water = ½ (a+b) kmph
    = ½ (6+2) = 8/2 = 4kmph

     


  5. Akansha can row upstream at 8 kmph and downstream at 12 kmph.What is the speed of the stream ?
    5 km/hr
    7 km/hr
    8 km/hr
    5 km/hr
    2 km/hr
    Option E
    Speed of the stream = ½ (x-y) = ½ (12-8)
    = 4/2 = 2 kmph

     


  6. Ramesh rows to a place 48 km distant and back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against stream. Find the rate of the stream?
    1 km/hr
    3 km/hr
    5 km/hr
    6 km/hr
    None of these
    Option A
    Speed of the stream = ½ (x-y) km/ hr
    Speed = distance traveled / time taken

     


  7. Shivani can row a boat at 10 kmph in still water. If the speed of the stream is 6 kmph, the time taken to row a distance of 80 km down the stream is ?
    is
    5 hours
    2 hours
    3 hours
    4 hours
    None of these
    Option A
    Speed in still water, ½ (a+b) = 10 km/hr
    a+b = 20 km/hr…………….(1)
    speed of the stream, ½ (x-y) = 6km/hr
    x-y = 12 km/hr …………….(2)
    (1)+(2 ) we get 2x = 32
    x= 16 km/hr
    speed downstream =distance traveled / time taken
    time taken = 80/16 = 5 hours

     


  8. Srikant can row 9 (1/3) kmph in still water and finds that it takes him thrice as much time to row up than as to row down the same distance in the river. What is speed of current ?
    4 (2/3) km/hr
    7 (2/3) km/hr
    5 (1/3) km/hr
    7 km/hr
    None of these
    Option A
    Speed in still water = 9 (1/3) = 28/3 km/hr
    i.e, ½ (x+y) = 28/3 km/hr
    =½ (x+3x) = 28/3
    2x = 28/3 = x = 28/ 2 x 3 = 14/3 km/hr
    rate upstream = 14/3 km/hr and
    rate downstream = 14/3 x 3 = 14 km/hr
    speed of the current = ½ (x-x) = ½ (14 – 14/3)
    = ½ (42-14/3) = 28/6 = 4 (2/3) km/hr

     


  9. Vikas goes downstream 60 km and upstream 20 km, taking 4 hrs each. What is the speed of current?
    8 km/hr
    5 km/hr
    10 km/hr
    2 km/hr
    4 km/hr
    Option B
    Downstream speed = 60/4 = 15 km/hr
    Upstream speed = 20/4 = 5 km/hr
    Speed of stream = (15-5)/2 = 5 km/hr

     


  10. Akash rows downstream 28 km and upstream 16 km, taking 5 hrs each time. What is the velocity of current?
    1.2 km/hr
    1.8 km/hr
    2 km/hr
    1.5 km/hr
    None of these
    Option A
