Total number of students appeared = 2400
The ratio of boys and girls appeared from school A is 5 : 6 and 60 % of the students who appeared from school E are girls. Total number of girls who appeared from schools A and E exceeds \(\frac{2}{3}\) of the total number of students who appeared from school B and D by \(x\). The value of \(x\) lies between:
Your Answer : (Not Answered)
Correct Answer : C
The value of x is 120, which lies between 115 and 125. The total is 2400 students. From the pie chart, school A has 22 % = 528, B has 16 % = 384, D has 17 % = 408 and E has 25 % = 600.
\[ \text{Girls in A} = \frac{6}{11} \times 528 = 288 \]
\[ \text{Girls in E} = 0.60 \times 600 = 360 \]
So the girls from A and E number 288 + 360 = 648. The students from B and D number 384 + 408 = 792, and two thirds of that is 528.
\[ x = 648 - 528 = 120 \]
The other ranges, 95 to 105, 105 to 115 and 125 to 135, do not contain 120.
At what time between 7 and 8 will the hands of a clock be in the same straight line but, not together?
Your Answer : (Not Answered)
Correct Answer : A
When the hands of the clock are in the same straight line but not together, they are 30 minute spaces apart.
At 7 o'clock, they are 25 min. spaces apart.
Minute hand must gain only 5 min. space.
55 min. spaces are gained in 60 min.
5 min. spaces would be gained in (60/55) x 5 = 5 (5/11) min
Required time = 5 (5/11) min past 7
Rice and wheat are in a mixture in the ratio 5:3. If 16 kg wheat is added to this mixture, the ratio of rice to wheat changes to 5:7. How much wheat is in new mixture?
Your Answer : (Not Answered)
Correct Answer : B
Let rice \( = 5k \) and wheat \( = 3k \). Adding 16 kg of wheat changes only the wheat.
\[ \frac{5k}{3k + 16} = \frac{5}{7} \quad\Longrightarrow\quad 35k = 15k + 80 \]
\[ 20k = 80 \quad\Longrightarrow\quad k = 4 \]
\[ \text{new wheat} = 3(4) + 16 = 28 \text{ kg} \]
The question asks for the wheat in the new mixture, not the original 12 kg.

Study the following information carefully to answer these questions.
P, Q, R, S, T, U, V and W are sitting around a circular table, facing the centre. P sits third to the right of W and third to the left of Q. S sits second to the right of T. V sits second to the left of R. T is not the neighbour of Q while U is neither a neighbour of T nor of W.
Who sits second to the left of V?
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: U
Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix P; W is three to P’s left and Q three to P’s right. Trying each seat for T with S two to T’s right, only one choice keeps T away from Q, and of the two ways of then placing R and V, only one keeps U away from both T and W. Clockwise the table reads P → T → R → W → V → Q → U → S.
Two seats to V’s left - clockwise - gives Q and then U.

If 4 x 9 x 3 = 4 and 5 x 3 x 1 = 3, then
9 x 9 x 7 = ?
Your Answer : (Not Answered)
Correct Answer : A
Correct answer: 5
In each case the three numbers are added and the square root taken: \( \sqrt{4+9+3} = \sqrt{16} = 4 \) and \( \sqrt{5+3+1} = \sqrt{9} = 3 \). So \[ \sqrt{9+9+7} = \sqrt{25} = \mathbf{5} \]

They will demolish the entire block.
Your Answer : (Not Answered)
Correct Answer : D
Correct answer: The entire block will be demolished by them.
The future will demolish becomes will be demolished. The continuous option makes it already under way, may turns a plan into a possibility, and will have to be adds an obligation the original does not state.
Choose the correct category of the underlined word:
It is very interesting to know your story.
Your Answer : (Not Answered)
Correct Answer : D
Interesting is an adjective here.
It follows the linking verb 'is' as a complement and describes the quality of 'to know your story': the experience is interesting. It is also modified by the adverb 'very', which modifies adjectives and adverbs.
It is not a noun or pronoun, since it names nothing, and not an adverb, since it describes no action; it is a participial adjective formed from the verb 'interest'.
Computer Awareness [ Question No: 10 To 12 ] :
In operating systems, internal fragmentation occurs when
Your Answer : (Not Answered)
Correct Answer : B
Correct answer: allocated memory is slightly larger than the requested memory, leaving unused space inside a block
Internal fragmentation is space wasted inside an allocated block, because memory is handed out in fixed units and the request rarely fills the last one exactly. A process needing 5 KB with a 4 KB page size receives two pages and wastes 3 KB. External fragmentation, the second option, is the opposite: enough free memory exists in total but it is scattered in pieces too small to satisfy a request. The distinction determines the remedy. Paging eliminates external fragmentation entirely, since any free frame will do for any page, but introduces internal fragmentation of at most one page per process - on average half a page. Contiguous allocation and segmentation avoid internal fragmentation but suffer external. Compaction cures external fragmentation by shuffling processes together to make one large hole, at considerable cost in copying, and only works if relocation is dynamic.
Which of the following section does not exist in a slide layout?

General Awareness / General Knowledge (GK) [ Question No: 13 To 20 ] :
Which of the following region of Rajasthan does not have very humid or humid climate?
Your Answer : (Not Answered)
Correct Answer : B
The region without a humid climate is Bikaner.
Bikaner lies in the Thar desert in north-western Rajasthan, with very low rainfall and an arid climate.
Udaipur and Sirohi in the south (Sirohi includes Mount Abu) and Kota in the south-east receive the state's highest rainfall and are classed among its humid and sub-humid climatic regions, so all three are wrong.
The following refers to a recent development in technology. "It makes it possible to easily alter DNA sequences and modify Gene function. It can therefore correct genetic defects and improve crops, but with associated ethical problems."
Which of the following is the recent development referred to above ?
Your Answer : (Not Answered)
Correct Answer : B
The development described is CRISPR.
CRISPR-Cas9 is a gene-editing technique adapted from a bacterial immune defence. A guide RNA directs the Cas9 enzyme to a chosen DNA sequence, where it cuts the DNA so that genes can be disabled, corrected or replaced. It is cheap and precise enough to be used to correct genetic defects and improve crops, and it raises ethical questions, especially over editing human embryos. Its developers, Jennifer Doudna and Emmanuelle Charpentier, received the 2020 Nobel Prize in Chemistry.
DNA barcoding identifies species from a short standard gene region. p53 is a tumour-suppressor gene. 'Terminator' technology makes seeds sterile so they cannot be replanted. None of them edits genes at will.

Primary Producers fall in two categories e.g.
Your Answer : (Not Answered)
Correct Answer : D
They are phototrophs and chemotrophs.
Both make their own food, differing only in the energy source: phototrophs such as green plants and cyanobacteria use sunlight, while chemotrophs such as the nitrifying and sulphur bacteria use energy released by oxidising inorganic compounds - which is how life persists in deep-sea vents where no light reaches.
