Joining Sentences

(B) Either you walk a bit faster or …..
(C) Unless you walk a bit faster …..

A. Only A
B. A and B
C. Only C
D. B and C
E. A and C

Explanation:
The two sentences are related to a condition (i.e) ‘if you walk fast you will catch the bus. Hence, conjunctions like, if and ‘unless’ can be used to combine the two sentences effectively. ‘Either … or’ is used to show a choice between two things which you would opt for. Here it is a condition where it is essential to walk faster if they have to catch the bus and not a choice.

C. Only B
D. B and C

The two sentences are linked with a cause and its reason. The use of ‘as’, ‘since’ and ‘because’ can combine the sentences meaningfully. The use of ‘if’ is incorrect as it denotes a condition in the future.

Error Correction (Phrase in colour)

19. You would not drive so fast; we have plenty of time.

A. will not
C. need not
D. do not
E. No correction required

Explanation:
The sentence suggests that driving fast is not necessary. Hence the most appropriate modal verb to suit this context would be ‘need not’. ‘Will not’ suggests a simple future which is inapt. ‘Had not’ and ‘do not’ are illogical.

20. To be overweighed is not the same as being obese.

A. Being overweighed
B. To be overweight
C. Being overweight
D. Being overweight
E. No correction required

Explanation:
The comparison is between ‘being overweight’ and ‘being obese’. As the second part of the sentence has ‘being obese’ parallelism demands that the first part also takes the same be-form. Hence, ‘being overweight’ is the correct way of expressing the idea.

21. Scientists have estimated that millions of creatures living in water had been dying every year if they become entangled in plastic pollution or ingest it.

A. every year is dying as
B. has died every year as if
C. die every year when
D. was dying every year when
E. No correction required

Explanation:
Scientists say that it happens ‘every year’. Hence it is most apt to use the simple present tense (die) in this context. Also the use of ‘if’ as the conjunction is illogical. They die ‘when they become entangled in’.

Para Completion

22. Stress is an inevitable part of sports. —- Absence of stress leads to apathy and a disinterested performance.
(A) Stress can be treated as a positive sign as well.
(B) Stress is not necessarily bad: it is, after all, the body’s way of rising to a challenge.
(C) During stress, the mind becomes alert, the muscles tense as if ready for a fight or flight and the heart, lungs, and metabolism gets ready to act.

A. Only A
B. Only B
C. Only C
D. A and B
E. All the three

Explanation:
The first statement states that stress cannot be avoided in sports. Statement C follows the first statement by elaborating on how stress is beneficial to the human body. The last sentence summarizes the paragraph by saying what the absence of stress would lead to. Thus only statement C forms a coherent paragraph with the two given statements.

23. If you are a doctor, one of the greatest honors to which you can aspire is to have a nightmarish disease named after you. —- Eponyms bring color, tradition, and culture to medicine and also provide a useful shorthand.
(A) Hundreds of so-called eponyms dot the medical textbooks, enshrining the name of a man or a woman who became the first to identify some horrible ailment, describe symptoms or devise a new diagnostic test.
(B) But the time-honored practice is under threat, judging by a fierce debate in the August 2007 issue of the British Medical Journal.
(C) Names, especially when it comes to obscure conditions or procedures, can cause confusion and are often historically untruthful, argue some of the anti-eponymists.

A. A and B
B. Only A
C. B and C
D. Only C
E. A and C

Explanation:
Sentence A follows the first sentence as it tells us what this practice of naming a disease after a person is called (i.e.) eponym. And the last sentence highlights on the importance of using such eponyms. Hence the given two sentences along with sentence A forms a logical paragraph. Sentences B and C express the idea of the anti-eponymists and their debate with the pro-eponymists which is not necessary in this context.

24. Chronic pain is common among older people. —- A new study has revealed that mind-body therapies such as yoga and meditation that cause interaction between the mind, body, and behavior can help the elderly get rid of chronic pain.
(A) The people suffering from chronic pain can help themselves with some mind-body therapies which include yoga, meditation, progressive muscle relaxation, and tai chi.
(B) Sufferers are often unable to receive adequate treatment because of limited physician training in pain management for the elderly and the increased likelihood of side effects from pain medication.
(C) The mind-body therapies are well suited even to the frail older adults because of their gentle approach.

A. Only A
B. Only B
C. Only C
D. A and B
E. B and C

Explanation:
The opening sentence talks about the relation between old age and chronic pain. Though without any other sentence the last sentence can follow the first to complete the idea, it is better to introduce sentence B in between as it gives a reason as to why the elderly people go in for mind-body therapies instead of another kind of treatment.

21. A can do a piece of work in 4 hours; B and C together can do it in 3 hours, while A and C together can do it in 2 hours. How long will B alone take to do it?

A. 8 hours
B. 10 hours
C. 12 hours
D. 24 hours

Explanation:

A’s 1 hour’s work = ($$\frac{1}{4}$$)

(B + C)’s 1 hour’s work = ($$\frac{1}{3}$$)

(A + C)’s 1 hour’s work = ($$\frac{1}{2}$$)

(A + B + C)’s 1 hour’s work = ($$\frac{1}{4}$$ + $$\frac{1}{3}$$) = ($$\frac{7}{12}$$)

B’s 1 hour’s work = ($$\frac{7}{12}$$ – $$\frac{1}{2}$$) = ($$\frac{1}{12}$$)
Therefore B alone will take 12 hours to do the work.

A. 3500
B. 4000
C. 4050
D. 5000

Explanation:

Let P, Q and R represent their respective monthly incomes. Then, we have:

P + Q = (5050 x 2) = 10100 …. (i)

Q + R = (6250 x 2) = 12500 …. (ii)

P + R = (5200 x 2) = 10400 …. (iii)

Adding (i), (ii) and (iii), we get: 2(P + Q + R) = 33000 or P + Q + R = 16500 …. (iv)

Subtracting (ii) from (iv), we get P = 4000.

P’s monthly income = Rs. 4000.

28. Sachin is younger than Rahul by 7 years. If their ages are in the respective ratio of 7 : 9, how old is Sachin?

A. 16 years
B. 18 years
C. 28 years
D. 24.5 years
E. None of these

Explanation:

Let Rahul’s age be x years.

Then, Sachin’s age = (x – 7) years.

$$\frac {x – 7}{x}$$ = $$\frac {7}{9}$$

9x – 63 = 7x

2x = 63

x = 31.5

Hence, Sachin’s age =(x – 7) = 24.5 years.

29. The least perfect square, which is divisible by each of 21, 36 and 66 is:

A. 213444
B. 214344
C. 214434
D. 231444

Explanation:

L.C.M. of 21, 36, 66 = 2772.

Now, 2772 = 2 x 2 x 3 x 3 x 7 x 11

To make it a perfect square, it must be multiplied by 7 x 11.

So, required number = 2$$^{2}$$ x 3$$^{2}$$ x 7$$^{2}$$ x 11$$^{2}$$= 213444

A. 35
B. 40
C. 45
D. 50

Explanation:

Let 1 man’s 1 day’s work = x and 1 woman’s 1 day’s work = y.

Then, 4x + 6y = $$\frac {1}{8}$$ and 3x + 7y = $$\frac {1}{10}$$.

Solving the two equations, we get: x = $$\frac {11}{400}$$ , y = $$\frac {1}{400}$$

1 woman’s 1 day’s work = $$\frac {1}{400}$$ .

10 women’s 1 day’s work = ($$\frac {1}{400}$$ x 10) = $$\frac {1}{40}$$ .

Hence, 10 women will complete the work in = 40 days.

35. A boat having a length of 3 m and breadth 2 m is floating on a lake. The boat sinks by 1 cm when a man gets on it. The mass of the man is:

A. 12 kg
B. 60 kg
C. 72 kg
D. 96 kg

Explanation:

Volume of water displaced = (3 x 2 x 0.01) m$$^{3}$$
= 0.06 m$$^{3}$$.
Mass of man = Volume of water displaced x Density of water
= (0.06 x 1000) kg
= 60 kg.

36. The effective annual rate of interest corresponding to a nominal rate of 6% per annum payable half-yearly is:

A. 6.06%
B. 6.07%
C. 6.08%
D. 6.09%

Explanation:

Amount of Rs. 100 for 1 year
when compounded half-yearly = Rs. (100 x (1 + $$\frac {3}{100})^{2}$$) = Rs. 106.09

Effective rate = (106.09 – 100)% = 6.09%

37. The present worth of a certain bill due sometime hence is Rs. 800 and the true discount is Rs. 36. The banker’s discount is:

A. Rs. 37
B. Rs. 37.62
C. Rs. 34.38
D. Rs. 38.98

Explanation:

B.G. =$$\frac {(T.D.)^{2}}{P.W.}$$ = Rs.$$\frac {36 \times 36}{800}$$= Rs. 1.62

B.D. = (T.D. + B.G.) = Rs. (36 + 1.62) = Rs. 37.62

38. The sum of the three numbers is 98. If the ratio of the first to second is 2 :3 and that of the second to the third is 5: 8, then the second number is:

A. 20
B. 30
C. 48
D. 58

Explanation:

Let the three parts be A, B, C. Then,

A : B = 2 : 3 and B : C = 5 : 8 = (5 x $$\frac {3}{5}$$) : (8 x $$\frac {3}{5}$$) = 3 : $$\frac {24}{5}$$

A : B : C = 2 : 3 : $$\frac {24}{5}$$ = 10 : 15 : 24
B = (98 x $$\frac {15}{49}$$) = 30.

39. A began a business with Rs. 85,000. He was joined afterward by B with Rs. 42,500. For how much period does B join, if the profits at the end of the year are divided in the ratio of 3: 1?

A. 4 months
B. 5 months
C. 6 months
D. 8 months

Explanation:

Suppose B joined for x months. Then,

Then, $$\frac {85000 \times 12 }{42500 \times x}$$ = $$\frac {3}{1}$$

x = $$\frac {85000 \times 12 }{42500 \times 3}$$ = 8.

So, B joined for 8 months.

40. How many 3 digit numbers are divisible by 6 in all?

A. 149
B. 150
C. 151
D. 166

Explanation:

Required numbers are 102, 108, 114, … , 996

This is an A.P. in which a = 102, d = 6 and l = 996

Let the number of terms be n. Then,

a + (n – 1)d = 996

102 + (n – 1) x 6 = 996

6 x (n – 1) = 894

(n – 1) = 149

n = 150.

41. A boatman goes 2 km against the current of the stream in 1 hour and goes 1 km along with the current in 10 minutes. How long will it take to go 5 km in stationary water?

A. 40 minutes
B. 1 hour
C. 1 hr 15 min
D. 1 hr 30 min

Explanation:

Rate downstream = $$\frac {1}{10}$$ x 60 km/hr = 6 km/hr.

Rate upstream = 2 km/hr.

Speed in still water = $$\frac {1}{2}$$ (6 + 2) km/hr = 4 km/hr.

Required time = $$\frac {5}{4}$$hrs = 1 $$\frac {1}{4}$$ hrs = 1 hr 15 min.

42. Two pipes A and B can fill a tank in 15 minutes and 20 minutes respectively. Both the pipes are opened together but after 4 minutes, pipe A is turned off. What is the total time required to fill the tank?

A. 10 min. 20 sec.
B. 11 min. 45 sec.
C. 12 min. 30 sec.
D. 14 min. 40 sec.

Explanation:

Part filled in 4 minutes = 4 ($$\frac {1}{15}$$ + $$\frac {1}{20}$$) = $$\frac {7}{15}$$.

Remaining part = (1 – $$\frac {7}{15}$$) = $$\frac {8}{15}$$.

Part filled by B in 1 minute = $$\frac {1}{20}$$

$$\frac {1}{20}$$ : $$\frac {8}{15}$$ :: 1 : x

x = ($$\frac {8}{15} \times 1 \times 20$$) = 10 $$\frac {2}{3}$$min = 10 min. 40 sec.

The tank will be full in (4 min. + 10 min. + 40 sec.) = 14 min. 40 sec.

43. (17)$$^{3.5}$$ x (17)$$^{?}$$ = 17$$^{8}$$

A. 2.29
B. 2.75
C. 4.25
D. 4.5

Explanation:

Let (17)$$^{3.5}$$ x (17)$$^{x}$$ = 17$$^{8}$$x.

Then, (17)$$^{3.5}$$ + x = 17$$^{8}$$.

3.5 + x = 8

x = (8 – 3.5)

x = 4.5

44. In how many different ways can the letters of the word ‘MATHEMATICS’ be arranged so that the vowels always come together?

A. 10080
B. 4989600
C. 120960
D. None of these

Explanation:

In the word ‘MATHEMATICS’, we treat the vowels AEAI as one letter.

Thus, we have MTHMTCS (AEAI).

Now, we have to arrange 8 letters, out of which M occurs twice, T occurs twice and the rest are different.

A number of ways of arranging these letters = $$\frac {8!}{(2!)(2!)}$$ = 10080.

Now, AEAI has 4 letters in which A occurs 2 times and the rest are different.

A number of ways of arranging these letters = $$\frac {4!}{2!}$$ = 12.

Required number of words = (10080 x 12) = 120960.

45. In a camp, there is a meal for 120 men or 200 children. If 150 children have taken the meal, how many men will be catered to with remaining meal?

A. 20
B. 30
C. 40
D. 50

Explanation:

There is a meal for 200 children. 150 children have taken the meal.

The remaining meal is to be catered to 50 children.

Now, 200 children = 120 men.

50 children = $$\frac {120}{200}$$ x 50 = 30 men.

46. A farmer traveled a distance of 61 km in 9 hours. He travelled partly on foot @ 4 km/hr and partly on bicycle @ 9 km/hr. The distance traveled on foot is:

A. 14 km
B. 15 km
C. 16 km
D. 17 km

Explanation:

Let the distance traveled on foot be x km.

Then, distance travelled on bicycle = (61 -x) km.

So, $$\frac {x}{4}$$ + $$\frac {(61 -x)}{9}$$ = 9

9x + 4(61 -x) = 9 x 36

5x = 80

x = 16 km.

47. A fires 5 shots to B’s 3 but A kills only once in 3 shots while B kills once in 2 shots. When B has missed 27 times, A has killed:

A. 30 birds
B. 60 birds
C. 72 birds
D. 90 birds

Explanation:

Let the total number of shots be x. Then,

Shots fired by A = $$\frac {5}{8}$$x

Shots fired by B = $$\frac {3}{8}$$x

Killing shots by A = $$\frac {1}{3}$$ of $$\frac {5}{8}$$ x = $$\frac {5}{24}$$x

Shots missed by B = $$\frac {1}{2}$$ of $$\frac {3}{8}$$ x = $$\frac {3}{16}$$x

$$\frac {3 \times x}{16}$$ = 27 or x = $$\frac {27 \times 16}{3}$$ = 144.

Birds killed by A = $$\frac {5x}{24}$$ = $$\frac {5}{24}$$ x 144 = 30.

48. A can run 22.5 m while B runs 25 m. In a kilometer race, B beats A by:

A. 100 m
B. 111$$\frac {1}{9}$$ m
C. 25 m
D. 50 m

Explanation:

When B runs 25 m, A runs $$\frac {45}{2}$$ m.

When B runs 1000 m, A runs ($$\frac {45}{2}$$ x $$\frac {1}{25}$$ x 1000) m = 900 m.

B beats A by 100 m.

49. If log10 5 + log10 (5x + 1) = log10 (x + 5) + 1, then x is equal to:

A. 1
B. 3
C. 5
D. 10

Explanation:

$$log_{10}$$ 5 + $$log_{10}$$ (5x + 1) = $$log_{10}$$ (x + 5) + 1

$$log_{10}$$ 5 + $$log_{10}$$ (5x + 1) = $$log_{10}$$ (x + 5) + $$log_{10}$$ 10

$$log_{10}$$ [5 (5x + 1)] = $$log_{10}$$ [10(x + 5)]

5(5x + 1) = 10(x + 5)

5x + 1 = 2x + 10

3x = 9

x = 3.

50. A hall is 15 m long and 12 m broad. If the sum of the areas of the floor and the ceiling is equal to the sum of the areas of four walls, the volume of the hall is:

A. 720
B. 900
C. 1200
D. 1800

h = $$\frac{180}{27}$$ m = $$\frac{20}{3}$$ m.
Volume = ($${15 \times 12 \times \frac {20}{3}}$$) m$$^{3}$$ = 1200 m$$^{3}$$.
