Quantitative Aptitude [ Question No: 1 To 4 ] :
At 40 past 4 in the evening, the smaller angle between the hour and minute hands of a clock is :
Your Answer : (Not Answered)
Correct Answer : D
The smaller angle is 100°.
The angle between the hands at H hours M minutes is \(|30H - 5.5M|\):
\[ \begin{aligned} |30 \times 4 - 5.5 \times 40| &= |120 - 220| \\ &= 100^\circ \end{aligned} \]
At 4:40 the minute hand points at 8 (240°) and the hour hand has moved two-thirds of the way from 4 to 5 (140°), so they are 100° apart. Forgetting the hour hand's movement gives 120°, which is not offered.
The value of \(\sin^2 25° + \sin^2 65°\) is:
Your Answer : (Not Answered)
Correct Answer : B
We use the complementary angle identity \(\sin(90° - \theta) = \cos \theta\).
\(\sin 65° = \sin(90° - 25°) = \cos 25°\).
The expression becomes \(\sin^2 25° + \cos^2 25°\).
Using the Pythagorean identity \(\sin^2 A + \cos^2 A = 1\), the value is 1.
In the special rule of addition of probability, the events are always
Your Answer : (Not Answered)
Correct Answer : B
The special rule of addition is
\[ P(A \cup B) = P(A) + P(B) \]
and it holds only when the events are mutually exclusive - they cannot both occur, so \( P(A \cap B) = 0 \) and there is no overlap to subtract.
Independence is the condition for the special rule of multiplication. The general addition rule, \( P(A \cup B) = P(A) + P(B) - P(A \cap B) \), needs no condition at all.
In the beginning, Ram works at a rate such that he can finish a piece of work in 24 hrs, but he only works at this rate for 16 hrs. After that, he works at a rate such that he can do the whole work in 18 hrs. If Ram is to finish this work at a stretch, how many hours will he take to finish this work?
Your Answer : (Not Answered)
Correct Answer : E
In the first 16 hours Ram works at \( \tfrac{1}{24} \) an hour.
\[ \frac{16}{24} = \frac{2}{3} \text{ of the work done} \]
The remaining \( \tfrac{1}{3} \) goes at \( \tfrac{1}{18} \) an hour:
\[ \frac{1}{3} \times 18 = 6 \text{ hours} \]
\[ 16 + 6 = 22 \text{ hours} \]

(e) Over the last few years, the average starting salaries of other professionals have increased by 20%.
Your Answer : (Not Answered)
Correct Answer : D
Correct answer: a,e,c
Take the three together and see whether they can all be true at once. If other professionals’ starting salaries have risen 20 percent, and the gap between teachers’ and theirs has nevertheless shrunk, then teachers’ salaries must have risen faster still - which supports the conclusion that starting teachers are no longer underpaid. The other sets mix in the average age of first-year teachers or the claim about formal education, neither of which bears on salary levels, so nothing follows from them.
Select the combination of letters that when sequentially placed in the blanks of the given series will complete the series. a _ z b _ y c _ x _ a z _ b y c c _ a a _ b b _ c c x _ a z _ b y _ c x
Your Answer : (Not Answered)
Correct Answer : A
The series is the block aaz bby ccx repeated. Placing abcabxzyabc in the 11 blanks in order gives a(a)zb(b)yc(c)x(a)az(b)bycc(x)aa(z)bb(y)ccx(a)az(b)by(c)cx, which reads aaz bby ccx aaz bby ccx aaz bby ccx aaz bby ccx without a break.
The other options put a letter other than the required one in an early blank. For example, acbacxzyabc makes the second block read bcy instead of bby, so the repeating pattern breaks.
A quick test of the key is that every third letter in the completed string runs z, y, x, then repeats, with the first letters running a, b, c in pairs.
Two statements labelled as Assertion (A) and Reason (R) are given. Read both the statements carefully and select the correct answer with the help of codes.
Assertion (A) : Earth is the only planet known to have life.
Reason (R) : Earth has an atmosphere which is a mixture of gases.
Your Answer : (Not Answered)
Correct Answer : A
The answer is Both (A) and (R) are true, but (R) is not the correct explanation of (A).
The Assertion is true: Earth is the only planet on which life is known to exist. The Reason is also true: Earth's atmosphere is a mixture of gases, mainly nitrogen and oxygen with argon, carbon dioxide and others.
But having an atmosphere that is a mixture of gases does not explain why Earth has life. Venus and Mars also have atmospheres of mixed gases and no known life. Life depends on a combination of factors, such as liquid water, a suitable temperature range, free oxygen and protection from radiation. So the Reason does not explain the Assertion.
A man pointing to a photograph says, "The lady in the photograph is my nephew's maternal grandmother." How is the lady in the photograph related to the man's sister who has no other sister ?
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: Mother
The man’s nephew is his sister’s son, so that boy’s maternal grandmother is the mother of the man’s sister - which is the man’s own mother. The lady is therefore the sister’s mother.
General Awareness / General Knowledge (GK) [ Question No: 9 To 18 ] :
Who of the following Padma Awardee from Rajasthan is associated with miniature painting ?
Your Answer : (Not Answered)
Correct Answer : D
The miniature painter is Tilak Geetai.
Tilak Gitai is known for traditional Rajasthani miniature painting and received the Padma Shri for it.
The others work in different crafts. Shree Lal Joshi is a master of Phad scroll painting, a narrative folk form rather than miniature painting. Mahesh Soni is known for Thewa, gold work on glass, and Ram Kishore Chhipa for hand block printing of textiles.
Who was the First Chief Justice of the Rajasthan High Court?
Your Answer : (Not Answered)
Correct Answer : D
The first Chief Justice of the Rajasthan High Court was Kamal Kant Verma, usually spelt Kamla Kant Verma.
The High Court of Rajasthan was set up in 1949 when the princely states of the region were merged, with its seat at Jodhpur. Verma was its first Chief Justice, and K. N. Wanchoo, later Chief Justice of India, followed him.
Kailash Nath Wanchoo held the office, but as the second Chief Justice, so option A is a near miss. S. K. Mittal and Arun Kumar Mishra are later judges, so they cannot be the first. The year of the court's creation is the quickest check against such distractors.
Your Answer : (Not Answered)
Correct Answer : B
A catalyst hastens the attainment of equilibrium.
It provides an alternative path of lower activation energy, and it lowers that barrier equally for the forward and the reverse reaction. Both rates therefore rise by the same factor, so equilibrium is reached sooner but its position - the value of \(K\) - is unchanged.

Your Answer : (Not Answered)
Correct Answer : D
The Saar is in Germany.
The Saar basin in the south-west, near the French border, is a major coalfield and was long the heart of German iron and steel. Its ownership was disputed between France and Germany through much of the twentieth century.
The minimum age of the voter in India is
Your Answer : (Not Answered)
Correct Answer : B
The minimum voting age in India is 18 years.
It was lowered from 21 by the 61st Amendment in 1988, which took effect for the 1989 general election and added about 50 million voters to the roll.
Microbiology [ Question No: 19 To 20 ] :
Under the Spaulding classification, an item contacting intact mucous membranes is
Your Answer : (Not Answered)
Correct Answer : C
Mucous membranes resist ordinary bacterial spores but are readily infected by other organisms, so high-level disinfection is accepted for items such as endoscopes and respiratory equipment. Sterilization is reserved for items that penetrate tissue.
A polysome is best defined as ________.
Your Answer : (Not Answered)
Correct Answer : A
Correct answer: several ribosomes translating one mRNA simultaneously
A polysome, or polyribosome, is a single mRNA being read at once by many ribosomes spaced along its length. It lets a cell produce many copies of a protein from one transcript, and in bacteria translation of the leading end begins while the far end is still being transcribed.
