Quantitative Aptitude [ Question No: 1 To 6 ] :
If the odds in favour of an event are 3:4, what is the probability of the event occurring ?
Your Answer : (Not Answered)
Correct Answer : A
The probability is 3/7.
Odds in favour of 3 : 4 mean 3 favourable outcomes for every 4 unfavourable ones, 7 in all. So the probability of the event is 3/(3 + 4) = 3/7.
4/7 is the probability of the event not happening, 3/4 is the odds written as a fraction, and 7/3 is greater than 1, which no probability can be.
In general, odds of a : b in favour give a probability of a/(a + b).
What is the value of
\[ (1+\frac12)(1+\frac13)(1+\frac14)\cdots(1+\frac1{24}) \;? \]
Your Answer : (Not Answered)
Correct Answer : C
Write each factor as a fraction: 1 + 1/2 = 3/2, 1 + 1/3 = 4/3, 1 + 1/4 = 5/4, and so on up to 1 + 1/24 = 25/24. The product is
\[ \frac{3}{2}\times\frac{4}{3}\times\frac{5}{4}\times\cdots \]
\[ \cdots\times\frac{25}{24} \]
Each numerator cancels the next denominator, so only the 25 at the end and the 2 at the beginning are left, giving 25/2 = 12.5. So the value is 12.5, option (C). The options 0.5, 10 and 25 do not come from the telescoping product.
If the first term of a G.P. is 5 and the sum of first three terms is 35/4. What is the common ratio?
Your Answer : (Not Answered)
Correct Answer : C
\[ S_{3} = a(1 + r + r^{2}) = \frac{35}{4} \]
\[ 1 + r + r^{2} = \frac{7}{4} \quad\Longrightarrow\quad 4r^{2} + 4r - 3 = 0 \]
\[ r = \frac{-4 \pm \sqrt{16 + 48}}{8} = \frac{-4 \pm 8}{8} \]
\[ r = \frac{1}{2} \quad\text{or}\quad r = -\frac{3}{2} \]
Both roots are valid common ratios, so both answers apply.
Find the one which does not belong to that group ?
Your Answer : (Not Answered)
Correct Answer : C
Three of the four are state capitals.
- Thiruvananthapuram - capital of Kerala
- Hyderabad - capital of Telangana
- Bangalore - capital of Karnataka
- Calicut (Kozhikode) - a city in Kerala, but not a capital
So Calicut does not belong. Note that Kerala appears twice in the list, which is the hint that being a capital, not the state, is the shared property.
A man wants to sell his scooter. There are two offers, one at Rs. 12,000 cash and the other a credit of Rs. 12,880 to be paid after 8 months, money being at 18% per annum. Which is the better offer?
Your Answer : (Not Answered)
Correct Answer : A
The present worth (PW) is what the sum is really worth today; the true discount (TD) is the interest that PW would earn over the remaining time:
\[ \text{Amount} = \text{PW}\left(1 + \frac{RT}{100}\right), \qquad \text{TD} = \text{Amount} - \text{PW} \]
Bring the credit offer back to today's money and then compare like with like.
\[ T = \frac{8}{12} = \frac{2}{3} \text{ year}, \qquad \frac{RT}{100} = \frac{18 \times 2/3}{100} = 0.12 \]
\[ \text{PW of the credit offer} = \frac{12880}{1.12} = 11500 \]
\[ 12000 > 11500 \]
The cash offer is worth Rs. 500 more in today's money, so Rs. 12,000 in cash is the better deal. The larger headline figure loses because eight months at 18% costs more than the extra Rs. 880 is worth.
In a race of 200 m, A can beat B by 31 m and C by 18 m. In a race of 350 m, C will beat B by :
Your Answer : (Not Answered)
Correct Answer : B
In these problems the two runners are compared by the distances they cover in the same time, so their speeds are in the ratio of those distances.
\[ A\,200 : B\,169, \qquad A\,200 : C\,182 \]
\[ C : B = 182 : 169 \]
In a 350 m race, when C finishes:
\[ B = 350 \times \frac{169}{182} = 325 \text{ m} \]
\[ \text{C beats B by } 350 - 325 = 25 \text{ m} \]

Your Answer : (Not Answered)
Correct Answer : D
Ours is a secular state does not mean that religion and religious values should be eradicated. In fact, these inculcate moral values. So, argument I is vague while argument II is strong. Also, teaching religion can in no way hinder the student's capability to face the challenges of the 21st century
At a buffet, six sweets are arranged in a circular order on a table. Burfi is opposite Halwa. There is one sweet between Laddu and Jalebi. Gulab jamun is to the right of Halwa. Rasagulla is one of the sweets. Which sweet is two places away to the left of Gulab jamun ?
Your Answer : (Not Answered)
Correct Answer : B
The sweet two places to the left of Gulab jamun is Rasagulla.
Seat the six sweets round the table in order, counting to the right. Put Halwa in place 1, so Burfi, opposite it, is in place 4. Gulab jamun is immediately to the right of Halwa, in place 2.
That leaves places 3, 5 and 6 for Laddu, Jalebi and Rasagulla. Laddu and Jalebi need exactly one sweet between them, which only places 3 and 5 allow (Burfi sits between them). So Rasagulla is in place 6.
Two places to the left of Gulab jamun (place 2) is place 6: one place left is Halwa, two places left is Rasagulla.
Halwa is only one place to the left, and Laddu and Jalebi sit on the other side of Gulab jamun.
Statement:
"Evaluation from the project guide, who is incharge of our project is very important to grade you favourably".
Assumptions:
I. The listeners are concerned about grades.
II. No other criterion is necessary to decide one's grades.
Your Answer : (Not Answered)
Correct Answer : A
The author of the statement is giving information about the grades of the listeners. This implies that the listeners are interested to know such information.Hence, (I) is an assumption. (II) is a generalization which cannot be assumed.

General Awareness / General Knowledge (GK) [ Question No: 13 To 19 ] :
Which pulse causes lathyrism when consumed on a regular basis ?
Your Answer : (Not Answered)
Correct Answer : A
Lathyrism is caused by Khesari dal.
Khesari dal (grass pea, Lathyrus sativus) contains a neurotoxin, beta-ODAP. Eating it as a staple over a long period, usually in times of drought when other pulses are scarce, causes lathyrism: a crippling paralysis of the lower limbs.
Chana (Bengal gram) and moong (green gram) do not contain this toxin, so 'None of the above' is also wrong. The disease is named after the plant's genus, Lathyrus.
Your Answer : (Not Answered)
Correct Answer : B
Carbon has four valence electrons.
Its configuration is \(1s^2\,2s^2\,2p^2\), so four electrons lie in the outermost shell. Having exactly half an octet, carbon neither gains nor loses electrons readily but shares all four - which is the root of the whole of organic chemistry.
Your Answer : (Not Answered)
Correct Answer : C
Because the refractive index of the different layers of the atmosphere keeps changing.
A star is effectively a point source, so its light passes through a narrow column of air. Turbulent cells of differing density bend the ray slightly and randomly, and the apparent position and brightness flicker. This is called atmospheric scintillation.
Your Answer : (Not Answered)
Correct Answer : B
Graphite is used as a moderator in nuclear reactors. Its job is to slow fast neutrons to thermal speeds, at which they are far more likely to cause further fission in uranium-235.
It works because carbon nuclei are light enough to take energy from a neutron in a collision but absorb very few neutrons themselves. Heavy water is the other common moderator.
Your Answer : (Not Answered)
Correct Answer : D
It is Mark Mazzetti.
The New York Times correspondent's The Way of the Knife, published in 2013, traces how the CIA turned from spying to killing after 2001, and how the military built an intelligence service of its own.
Your Answer : (Not Answered)
Correct Answer : B
Bal Gangadhar Tilak has not received the Bharat Ratna.
The award was instituted in 1954, some thirty-four years after his death, and although it has been given posthumously since 1966 he has never been named. Radhakrishnan received it in 1954, Shastri in 1966, Indira Gandhi in 1971 and Patel in 1991.
The Fundamental Rights as contained in our Constitution are grouped under ______ categories
Your Answer : (Not Answered)
Correct Answer : B
The fundamental rights fall under six heads: equality, freedom, freedom of religion, cultural and educational rights, the right against exploitation, and the right to constitutional remedies.
There were seven until the 44th Amendment of 1978 removed the right to property from Part III and made it a constitutional legal right under Article 300A.
Current Affairs [ Question No: 20 To 20 ] :
Which one of the following is an 'Air-to-Air' missile ?
Your Answer : (Not Answered)
Correct Answer : A
The air-to-air missile is Astra.
Astra, developed by DRDO, is India's indigenous beyond-visual-range air-to-air missile, fired from fighter aircraft such as the Su-30MKI to destroy enemy aircraft at long range.
Akash is a surface-to-air missile, fired from the ground at aircraft. Prithvi is a surface-to-surface ballistic missile. Becquerel is not a missile at all: it is the SI unit of radioactivity, one nuclear decay per second.
