A. 3.6
B. 7.2
C. 8.4
D 10
Answer: Option B
Explanation:
Speed = (600/5*60)m/sec =2m/sec.

5. An airplane covers a certain distance at a speed of 240 km in 5 hours. To cover the same distance in 1 hour, it must travel at a speed of:
A. 300kmph
B. 360kmph
C. 600kmph
D. 720kmph
Answer: Option D
Explanation:
Distance = (240 x 5) = 1200 km.
Speed = Distance/Time
Speed = 1200/(5/3) km/hr. [We can write 1 hours as 5/3 hours]
Required speed = | 1200 x | 3 | km/hr | = 720 km/hr. | |

6. A can do a work in 15 days and B in 20 days. If they work on it together for 4 days, then the fraction of the work that is left is :
A. 1/4
B. 1/10
C. 7/15
D. 8/15
Answer: Option D
Explanation:
A’s 1 day’s work = 1/15
B’s 1 day’s work = 1/20
(A + B)’s 1 day’s work = (1/15+1/20
(A + B)’s 4 day’s work = (7/60*4) = 7/15
Therefore, Remaining work =(1-7/15) = 8/15
7. Out of 7 consonants and 4 vowels, how many words of 3 consonants and 2 vowels can be formed?
A. 24400
B. 21300
C. 210
D. 25200
Answer: Option D
Explanation:
Number of ways of selecting 3 consonants from 7
= 7C3
Number of ways of selecting 2 vowels from 4
= 4C2
Number of ways of selecting 3 consonants from 7 and 2 vowels from 4
= 7C3 × 4C2
=(7×6×53×2×1)×(4×32×1)=210=(7×6×53×2×1)×(4×32×1)=210
It means we can have 210 groups where each group contains total 5 letters (3 consonants and 2 vowels).
Number of ways of arranging 5 letters among themselves
=5!=5×4×3×2×1=120=5!=5×4×3×2×1=120
Hence, required number of ways
=210×120=25200
8. In a group of 6 boys and 4 girls, four children are to be selected. In how many different ways can they be selected such that at least one boy should be there?
A. 159
B. 209
C. 201
D. 212
Answer: Option B
Explanation:
In a group of 6 boys and 4 girls, four children are to be selected such that at least one boy should be there.
Hence we have 4 options as given below
We can select 4 boys …(option 1)
Number of ways to this = 6C4
We can select 3 boys and 1 girl …(option 2)
Number of ways to this = 6C3 × 4C1
We can select 2 boys and 2 girls …(option 3)
Number of ways to this = 6C2 × 4C2
We can select 1 boy and 3 girls …(option 4)
Number of ways to this = 6C1 × 4C3
Total number of ways
= 6C4 + 6C3 × 4C1 + 6C2 × 4C2 + 6C1 × 4C3
= 6C2 + 6C3 × 4C1 + 6C2 × 4C2 + 6C1 × 4C1[∵ nCr = nC(n-r)]
=6×52×1+6×5×43×2×1×4=6×52×1+6×5×43×2×1×4 +6×52×1×4×32×1+6×4+6×52×1×4×32×1+6×4
=15+80+90+24=209

4. Each galaxy is surrounded by a giant sphere of dark matter more than 10 times so wide as the visible portion of the galaxy.
A. the width of
B. so wider than
C. of the width to
D. in width than
E. No correction required
Answer: Option A
Explanation:
It is ‘more than 10 times the width of’ something else. It has to take a noun and not an adjective. The comparison is between the width of the dark matter and the width of the visible portion of the galaxy. The comparison is brought out with the use of ‘more than’. Hence the use of ‘as wide as’ or ‘wider than’ becomes absurd. The correction is ’10 times of the width of’.

A. Only A
B. A and C
C. Only B
D. B and C
E. All the three
Answer: Option A
Explanation:
The first sentence says that women’s boxing has not been recognized as an Olympic sport. Sentence A follows with the idea that the IBA is campaigning towards including it in the 2008 Olympics. Taking up boxing as a profession or getting a government job as mentioned in sentences B and C cannot be a great ‘dream’ to be fulfilled which is the idea stated in the last sentence.
10. Male Vanity is no different from female’s —— in Face, a confident man no longer shies away from stating his deep interest in beautifying his appearance.
A. A and B
B. A and C
C. Only C
D. All the three
E. None of these.
Answer: Option D
Explanation:
The opening sentence talks about ‘male vanity’. The last sentence states that he doesn’t ‘shy away’ anymore. Hence we need something in between to make it more coherent. In fact, the opening and the last sentence along with all the three given choices make a complete paragraph as the idea of feel good, look good expressed in C is followed by the interest shown by man in the final sentence.
11. If you can’t give every student a computer, at least give them a mouse each. —– This seems to be the reason behind Microsoft Research Lab India’s development of a software solution that allows the use of multiple mice in a computer.

B. Only A
C. Only B
D. Only C
E. All the three
Answer: Option C
Explanation:
12. The opening sentence introduces us to the idea of using multiple mice in a computer. Sentence B tells us its benefits have been the reason for the development of this software by the Microsoft. This has nothing to do with the statistics given in A. Sentence C defines the product and hence can follow the last sentence.
Although the share of agriculture in the overall GDP has declined from around 40 per cent in 1980- 81 to below 20 per cent in 2006-07, its importance to the Indian economy can hardly be over emphasized. ——– In the context of ensuring food security and promoting inclusive growth, strategies to revitalize agriculture has become highly relevant.
A. A and B
B. Only A
C. B and C
D. Only C
E. Only B
Answer: Option D
Explanation:
The opening sentence highlights the importance of agriculture in the Indian economy. Sentence C follows emphasizing the fact that volatility in agriculture production can have various undesirable impacts. Hence we have to revitalize the agricultural field and this is the idea given in the last sentence. The other two sentences talk about ‘fiscal deficits’ and infrastructure deficiencies in the agricultural sector which are irrelevant in the given context.
13. Poverty is hitting increasing numbers of women, and it is hitting them harder, —- The percentage of female-headed households varies from thirty to forty percent in some south and south-east Asian countries, to almost half of all households in developing as well as in industrial countries.
A. Only A
B. A and B
C. Only B
D. Only C
E. All the three
Answer: Option A
Explanation:
Only statement A can be inserted between the two given sentences. The first sentence talks about increasing number of women being hit hard by poverty.

A. I alone is sufficient while II alone is not sufficient
B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Neither I nor II is sufficient
E. Both I and II are sufficient
Answer: Option E
Explanation:
From both I and II, we find that Rahul is (35 – 25) = 10 years older than his brother, who was born in 1964. So, Rahul was born in 1954.
2 Question: What will be the total weight of 10 poles, each of the same weight ?
Statements:
One-fourth of the weight of each pole is 5 kg.
The total weight of three poles is 20 kilograms more than the total weight of two poles.
A. I alone is sufficient while II alone is not sufficient
B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Neither I nor II is sufficient
E. Both I and II are sufficient
Answer: Option C
Explanation:
From I, we conclude that weight of each pole = (4×5) kg = 20 kg.
So, total weight of 10 poles = (20 x 10) kg = 200 kg.
From II, we conclude that:
Weight of each pole = (weight of 3 poles) – (weight of 2 poles) = 20 kg.
So, total weight of 10 pojes = (20 x 10) kg = 200 kg.

B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Neither I nor II is sufficient
E. Both I and II are sufficient
Answer: Option E
Explanation:
From I, total sale of product A = Rs. (8000 x 25) = Rs. 200000.
From II, we know that the company deals only in product A.
This implies that sale of product A is the total sale of the company, which is Rs. 200000.
5. Question: The last Sunday of March, 2006 fell on which date ?
Statements:

B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Neither I nor II is sufficient
E. Both I and II are sufficient
Answer: Option C
Explanation:
From I, we conclude that 5th, 12th, 19th and 26th of March, 2006 were Sundays.
So, the last Sunday fell on 26th.
From II, we conclude that 31st March, 2006 was Friday. Thus, 26th March, 2006 was the last Sunday of the month.

B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Neither I nor II is sufficient
