Quantitative Aptitude [ Question No: 1 To 4 ] :
A and B can complete a work individually in 12 days and 18 days. They started doing the work together but after 4 days A had to leave and B alone completed the remaining work. The whole work was completed in
Your Answer : (Not Answered)
Correct Answer : C
The whole work was completed in 12 days.
In 4 days together they do
\[ \begin{aligned} 4\left(\frac{1}{12} + \frac{1}{18}\right) &= 4 \times \frac{5}{36} \\ &= \frac{5}{9} \end{aligned} \]
The remaining \(\frac{4}{9}\) is done by B alone at \(\frac{1}{18}\) per day, taking \(\frac{4}{9} \times 18 = 8\) days. The total is 4 + 8 = 12 days.
8 days is only B's share, the usual slip; 20 and 30 days are longer than B would take to do the whole job alone.
It is observed that January 1, 2023 is a Sunday. In which year again the January 1st will fall on a Sunday?
Your Answer : (Not Answered)
Correct Answer : C
January 1st next falls on a Sunday in 2034.
Each ordinary year moves the weekday of January 1 forward by one day, and a leap year by two. Starting from Sunday in 2023:
- 2024 Monday; 2025 Wednesday (2024 is a leap year); 2026 Thursday; 2027 Friday; 2028 Saturday
- 2029 Monday (2028 is a leap year); 2030 Tuesday; 2031 Wednesday; 2032 Thursday
- 2033 Saturday (2032 is a leap year); 2034 Sunday
The list shows that 2029 starts on a Monday and 2030 on a Tuesday; continuing, 2035 is Monday, 2036 Tuesday and 2037 Thursday (2036 is a leap year), so none of the other options works. Ignoring leap years would wrongly give 2030, seven years on.
The number 897159*2 is divisible by 4. What is the sum of all possible values of *?
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: 25
A number is divisible by 4 when the number formed by its last two digits is divisible by 4. Here those digits are *2, so we need the two-digit endings 02, 12, 22, ... , 92 that 4 divides.
\[12 = 4\times 3,\quad 32 = 4\times 8,\quad 52 = 4\times 13,\quad 72 = 4\times 18,\quad 92 = 4\times 23\]
The remaining endings - 02, 22, 42, 62 and 82 - are each 2 more than a multiple of 4, so they fail. The admissible values of * are therefore 1, 3, 5, 7 and 9, and their sum is \(1+3+5+7+9 = 25\).
The area of a square field is 3136 sq. m. Barbed wire is to be drawn 3 rounds around the field at the rate of Rs. 1.50 per metre. Two gates of 1 m width each are to be left for entrance. What is the total cost?
Your Answer : (Not Answered)
Correct Answer : C
Find the side, then the length of wire once the gates are deducted.
\[ \text{side} = \sqrt{3136} = 56 \text{ m} \quad\Longrightarrow\quad \text{perimeter} = 224 \text{ m} \]
Two gates of 1 m each are left open:
\[ 224 - 2 = 222 \text{ m per round} \]
\[ \text{total wire} = 222 \times 3 = 666 \text{ m} \]
\[ \text{cost} = 666 \times 1.50 = \text{Rs. } 999 \]
The gates must be subtracted before multiplying by the three rounds, since every round skips them.

Study the following information carefully to answer these questions.
A, B, C, D, E, F, G and H are sitting around a circle, facing the centre. F sits to the immediate right of D and third to the left of A. G sits third to the left of D who does not sit next to E. B sits next to G but not next to D. C does not sit next to either D or A.
Which of the following pairs sits between G and D?
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: HB
Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix D; F takes the seat on D’s right, and since F is three to A’s left, A is fixed too, as is G three to D’s left. B must sit beside G but not beside D; C may touch neither D nor A; and E may not touch D. Those three conditions leave only one filling. Clockwise the circle reads D → H → B → G → A → E → C → F.
Between G and D, counting the short way round, sit B and then H - the pair HB. The other side of the circle holds five people, so this is the pair the question means.
Direction for [ Question No: 6 To 6 ] :
P, Q, R, S, T and U are travelling in a bus.
(ii). There are two reporters, two technicians, one photographer and one writer in the group.
(iii). The photographer P is married to S who is a reporter.
(iv). The writer is married to Q who is of the same profession as that of U.
(v). P, R, Q, S are two married couples and nobody in the group has same profession.
(vi). U is brother of R.
Which of the following is a pair of technicians ?
Your Answer : (Not Answered)
Correct Answer : D
P is a photographer.
P is married to S. So, one couple is PS. Then, the other couple is RQ.
S is a reporter.
The writer is married to Q. So, R is the writer. Now, P, Q, R, S have different professions. So, Q is a technician and thus U is also a technician.
U is the brother of R.
We now know the professions of P, Q, R, S and U. Only T remains. Since there are two reporters in the group, so T is also a reporter.
Hence, Q and U are technicians.
Look at the gaps between successive letters rather than at the letters themselves, and complete the sequence.
B, C, E, H, L, ?
Your Answer : (Not Answered)
Correct Answer : B
Correct answer: Q
The differences increase by one at every step: B to C is +1, C to E is +2, E to H is +3, H to L is +4, so the next must be +5. Five beyond L(12) is position 17, giving Q. Note that the terms are at positions 2, 3, 5, 8, 12, 17 - each is the previous plus the running count. P at 16 would follow from repeating the +4 step instead of increasing it. The running total of the gaps is 1, 3, 6, 10, 15 - the triangular numbers - so the position of the nth term is always the starting position plus a triangular number.
A bus for Delhi leaves every thirty minutes from a bus stand. An enquiry clerk told a passenger that the bus had already left ten minutes ago and the next bus will leave at 9.35 a.m. At what time did the enquiry clerk give this information to the passenger?
Your Answer : (Not Answered)
Correct Answer : D
Correct answer: 9.15 a.m.
Buses leave every thirty minutes, so the one before the 9.35 bus left at 9.05. That bus had gone ten minutes earlier, which puts the conversation at \[ 9.05 + 10\text{ min} = \mathbf{9.15\ a.m.} \]
English Language [ Question No: 9 To 10 ] :
There is a wall _____ the garden.
Your Answer : (Not Answered)
Correct Answer : A
The sentence reads There is a wall around the garden.
Around means on every side of something, enclosing it, which is what a garden wall does.
On the garden would put the wall on top of the garden's surface, across the garden would mean a wall cutting through it from one side to the other, and into shows movement towards the inside of something, which a fixed wall does not have.
Select the most appropriate option to substitute the underlined segment in the given sentence. If no substitution is required, select ‘No improvement’ as your answer.
The TV channel pack which us subscribed to is renewed monthly.
Your Answer : (Not Answered)
Correct Answer : C
The underlined words 'which us subscribed to' are wrong, since us is an object form that cannot be the subject. The relative clause needs the subject we and a verb form that agrees: 'that we subscribe to' is correct, and it fits 'The TV channel pack that we subscribe to is renewed monthly'. The options 'we are subscribed on' and 'we are subscribed with' use a wrong preposition and a passive verb, and 'No improvement' leaves the error. The answer is option (C).
Computer Awareness [ Question No: 11 To 16 ] :
Which of the following is not an example of cloud storage ?
Your Answer : (Not Answered)
Correct Answer : C
The one that is not cloud storage is Microsoft Edge.
Microsoft Edge is a web browser. It can be used to reach cloud services, but it does not store files itself.
Google Drive and pCloud are cloud storage services for files, and Microsoft Azure is a cloud computing platform whose services include cloud storage (such as Azure Blob Storage).
The slide that is used to introduce a topic and set the tone for the presentation is called the
Your Answer : (Not Answered)
Correct Answer : D
Correct answer: title slide
The title slide is the opening layout, carrying the presentation title and a subtitle. It names the topic and sets the tone before any content appears. A bullet slide carries the body points, while table and graph slides present data later in the deck.
Which of the following topologies is not of broadcast type?
Your Answer : (Not Answered)
Correct Answer : B
Correct answer: Star
In bus and ring topologies a signal reaches every station, so both are broadcast arrangements. In a star the central device receives each transmission and passes it on only where it is needed, so it is not inherently broadcast.
In analyzing the compilation of PL/I program, the term "Machine independent optimization" is associated with
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: creation of more optimal matrix.
Improving the intermediate representation - removing common subexpressions, hoisting loop-invariant code, folding constants - is done before any target machine is considered, so it belongs to machine-independent optimisation. Register allocation and instruction selection depend on the machine and come later.
A page fault
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: is an access to a page not currently in memory
A page fault is the trap raised when a program references a page that is not resident: the hardware interrupts, the operating system finds the page on disk, brings it into a free frame - evicting another page if necessary - updates the page table and restarts the instruction. It is a normal event in a paged system, not an error.
Word "INTERPRETER" is related to ?
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: Programming Languages
An interpreter takes a program in a high-level language and executes it statement by statement, translating each one as it reaches it rather than producing a machine-code file first. That makes it slower than a compiled program but easier to test, since a change can be run at once.
General Awareness / General Knowledge (GK) [ Question No: 17 To 20 ] :
In which State of India has the first National Sports University been set up ?
Your Answer : (Not Answered)
Correct Answer : B
India's first National Sports University was set up in Manipur.
The National Sports University at Imphal, Manipur, was established first by ordinance in 2018 and then by the National Sports University Act, 2018, as a central university for sports sciences, sports technology, sports management and coaching.
Madhya Pradesh, Meghalaya and Maharashtra do not host the national university. Some states have set up their own state sports universities, but the first central National Sports University is the one in Manipur.
Your Answer : (Not Answered)
Correct Answer : A
The order is \(\mathrm{N^{3-} > O^{2-} > F^- > Na^+}\).
All four are isoelectronic, each having 10 electrons, so the size depends only on the nuclear charge pulling them in: \[\mathrm{N}\ (Z=7) < \mathrm{O}\ (8) < \mathrm{F}\ (9) < \mathrm{Na}\ (11)\] The larger the nuclear charge for the same electron count, the smaller the ion - so radius falls as \(Z\) rises.
On which among the following dates, Army Day is observed?
Your Answer : (Not Answered)
Correct Answer : A
15 January is Army Day in India.
It marks the day in 1949 when Field Marshal K.M. Cariappa took over as the first Indian commander-in-chief of the Indian Army from General Sir Francis Butcher, the last British holder of the post.
What was the real name of Chanakya ?
Your Answer : (Not Answered)
Correct Answer : C
It was Vishnugupta.
The Arthashastra colophon names its author Vishnugupta; Chanakya is the patronymic, from his father Chanaka, and Kautilya the gotra name. All three refer to the Brahmin of Takshashila who set Chandragupta on the Magadhan throne.
