Quantitative Aptitude [ Question No: 1 To 3 ] :
2 men and 3 boys can do a piece of work in 10 days while 3 men and 2 boys can do the same work in 8 days. In how many days can 2 men and 1 boy do the work?
Your Answer : (Not Answered)
Correct Answer : C
Let 1 man's 1 day's work be 'm' and 1 boy's 1 day's work be 'b'. From the problem, \(10(2m+3b)=1\) and \(8(3m+2b)=1\). So, \(20m+30b=24m+16b \Rightarrow 4m=14b \Rightarrow m=3.5b\). Substitute this in the first equation: \(2(3.5b)+3b = 1/10 \Rightarrow 7b+3b=1/10 \Rightarrow 10b=1/10 \Rightarrow b=1/100\). Then \(m=3.5/100 = 7/200\). We need to find the time for 2 men and 1 boy. Their combined work per day is \(2m+1b = 2(7/200) + 1/100 = 14/200 + 2/200 = 16/200 = 2/25\). So, they will take 25/2 = 12.5 days.
The compound interest accrued on an amount of Rs.44000 at the end of two years is Rs.1193.60. What would be the simple interest accrued on the same amount at the same rate in the same period?
Your Answer : (Not Answered)
Correct Answer : C
Let the rate of interest be R% p.a.
4400{[1 + R/100]² - 1} = 11193.60
[1 + R/100]² = (44000 + 11193.60)/44000
[1 + R/100]² = 1 + 2544/1000 = 1 + 159/625
[1 + R/100]² = 784/625 = (28/25)2
1 + R/100 = 28/25
R/100 = 3/25
Therefore R = 12 SI on Rs.44000 at 12% p.a. for two years = 44000(2)(12)/100
=Rs.10560
\((1000)^{9} \div 10^{24} = ?\)
Your Answer : (Not Answered)
Correct Answer : B
Write the numerator as a power of ten.
\[ (1000)^{9} = (10^{3})^{9} = 10^{27} \]
\[ \frac{10^{27}}{10^{24}} = 10^{3} = 1000 \]
Computer Awareness [ Question No: 4 To 9 ] :
Which of the following is not a class based on size?
Your Answer : (Not Answered)
Correct Answer : D
Correct answer: Digital Computer
Mainframe, mini and micro are the classes defined by size and capacity. Digital describes how a computer represents data - as against analogue - and says nothing about how big it is.
Which shortcut key is used To change line height to 1.5 ?
Your Answer : (Not Answered)
Correct Answer : D
Correct answer: Ctrl + 5
The line-spacing shortcuts are Ctrl + 1 for single, Ctrl + 2 for double and Ctrl + 5 for one-and-a-half - the 5 standing for 1.5.
In a relational schema, each tuple is divided into fields called
Your Answer : (Not Answered)
Correct Answer : A
Correct answer: Domains
A relation is defined over a set of attributes, each drawn from a domain - the set of permitted values for that field. So the fields into which a tuple divides correspond to the domains of the relation. Relations are the tables themselves, one level up.
If a 3-input OR gate has eight input possibilities, how many of those possibilities will result in a HIGH output?
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: 7
An OR output is LOW only when every input is LOW, and of the eight combinations of three inputs just one is all-zero. The remaining seven give a HIGH output.
Sometimes the overhead of keeping track of a hole might be :
Your Answer : (Not Answered)
Correct Answer : B
Correct answer: larger than the hole itself
A hole must be recorded in the free list, and if the hole is very small the record costs more memory than the hole would ever supply. Such holes are therefore left attached to the allocated block, which converts external fragmentation into internal.
Which of following is corrected extension of a database file ?
Your Answer : (Not Answered)
Correct Answer : A
Correct answer: .db
.db is the generic database file extension, used by SQLite among others. The other three are not standard database extensions.
General Awareness / General Knowledge (GK) [ Question No: 10 To 20 ] :
Your Answer : (Not Answered)
Correct Answer : A
It represents the species.
The second word is the specific epithet, written in lower case, and it identifies the species within its genus. It is never used alone - sapiens means nothing without Homo.
Your Answer : (Not Answered)
Correct Answer : C
Chemical evolution holds that life could have arisen from the combination of chemicals under early-earth conditions.
Oparin and Haldane proposed it in the 1920s; Miller and Urey tested it in 1953 by passing electric sparks through a mixture of methane, ammonia, hydrogen and water vapour and obtaining amino acids.
Your Answer : (Not Answered)
Correct Answer : C
A string of binary digits specifying an operation is an instruction code.
It divides into the operation code, which says what to do, and the address field, which says what to do it to.
Your Answer : (Not Answered)
Correct Answer : C
Nitrous oxide (N2O) is the oxide of nitrogen used as an anaesthetic. Known as laughing gas, it has been used in dentistry and surgery since the 1840s.
Nitric oxide and nitrogen dioxide are toxic, and nitrogen pentoxide is an unstable solid that reacts violently with water - none of them could be breathed.

Correct Answer : A
It is Uttara.
Buddhadeb Dasgupta's 2000 film about two wrestlers in a Bengal railway village won him the Silver Lion for direction at Venice. Krantiveer, Mohra and 1942: A Love Story are Hindi commercial films by other directors.
Your Answer : (Not Answered)
Correct Answer : A
The Bharat Ratna is India's highest award.
Instituted in 1954, it is conferred for exceptional service of the highest order in any field. It carries no title and no monetary grant, only a sanad and a peepal-leaf medallion. The Padma Bhushan ranks third, after the Padma Vibhushan.
The water cycle process by which water changes from liquid to vapour is called
Your Answer : (Not Answered)
Correct Answer : D
Correct answer: Evaporation
Evaporation is the change from liquid to vapour, and it is what lifts water into the atmosphere - overwhelmingly from the oceans, which supply the great majority of atmospheric moisture. It is driven by solar energy and proceeds faster with higher temperature, lower humidity, and more wind, since moving air carries saturated air away from the surface. Water taken up by plant roots and released through the leaves is transpiration, and the two together are often measured as evapotranspiration. The rest of the cycle follows: rising moist air cools until the vapour condenses into cloud droplets, which grow and fall as precipitation, and the water then runs off, infiltrates the soil or evaporates again. A point worth noting is that evaporation leaves dissolved salts behind, which is why the oceans are saline and rainfall is fresh.
Your Answer : (Not Answered)
Correct Answer : A
The craton is the stable interior of a continent, made up of the ancient crystalline basement rock together with the flat-lying sedimentary platform that covers much of it.
A shield is only the part of the craton where the basement is exposed at the surface, so it is a portion of the craton rather than the whole of it.
Quartzite is metamorphosed from:
Your Answer : (Not Answered)
Correct Answer : A
Quartzite is metamorphosed sandstone.
Heat and pressure fuse the quartz grains until the rock breaks across the grains rather than around them, making it extremely hard and resistant. Limestone under the same conditions gives marble, and shale gives slate.
Which of the following groups of rivers have their source of origin in Tibet?
Your Answer : (Not Answered)
Correct Answer : C
The Brahmaputra, Indus and Sutlej rise in Tibet.
All three originate near Lake Mansarovar and Mount Kailash and then cut through the Himalayas, so they are older than the mountains they cross - antecedent rivers that kept their courses as the range rose around them.
The nature of the anti-Imperialist struggle was
Your Answer : (Not Answered)
Correct Answer : B
The anti-imperialist struggle was initially constitutional and by and large non-violent.
The early Congress worked through petitions and resolutions; from 1920 Gandhi turned it into a mass movement based on non-violent non-cooperation. Armed revolutionary activity ran alongside it but was never the main current.
