Show Answer

Answer: ((c))

Only III is sufficient

Using the following notations, we can draw the Family Tree,

From statement I:

F is the husband of A and S is the son of B.

The relation between F and S cannot be determined here.

Therefore, the statement I alone is not sufficient to answer the question.

From statement II:

F is a father of E and D is a sister of S.

The relation between F and S cannot be determined here.

Therefore, statement II alone is not sufficient to answer the question.

From statement III:

F is a husband of S’s father’s sister.

So, we get that F is the uncle of S.

Therefore, statement III alone is sufficient to answer the question.

On combining I and II:

The relation between F and S cannot be determined here.

Therefore, the statement I and II together are not sufficient to answer the question.

Hence, statement III alone is sufficient to answer the question.

Show Answer

Answer: ((e))

Only II and III are sufficient

From statement I:

X and Y are taller than U.

U < X, Y

Therefore, statement I alone is not sufficient to answer the question.

From statement II:

X is taller than U but shorter than S. W is tallest than all seven friends.

U < X < S

S, T, U, V, X and Y < W

Therefore, statement II alone is not sufficient to answer the question.

From statement III:

V is shorter than T but taller than S. Y is taller than T.

S < V < T < Y

Therefore, statement III alone is not sufficient to answer the question.

On combining I and II:

U < X, Y

U < X < S

S, T, U, V, X and Y < W

Therefore, statement I and II together are not sufficient to answer the question.

On combining I and III:

U < X, Y

S < V < T < Y

Therefore, statement I and III together are not sufficient to answer the question.

On combining II and III:

U < X < S

S, T, U, V, X and Y < W

S < V < T < Y

Thus, final arrangement is as follows:

U < X < S < V < T < Y < W

Therefore, V is at fourth tallest.

Hence, statement II and III together are sufficient to answer the question.

What type of switching is used by the internet?

((a))
Packet switching
((b))
Circuit switching
((c))
Telephone switching
((d))
Telex switching
((e))
None of these

Show Answer

Answer: ((a))

Packet switching

The correct answer is Packet switching

Important Points

The internet uses packet switching method. It groups the data into some small-sized packets and then the data is sent according to each packet separately.

Key Points

Packet Switching transmits data across digital networks by breaking it down into blocks or packets for more efficient transfer using various network devices. Each time one device sends a file to another, it breaks the file down into packets so that it can determine the most efficient route for sending the data across the network at that time. The network devices can then route the packets to the destination where the receiving device reassembles them for use.
Circuit switching is the most familiar technique used to build a communications network. It is used for ordinary telephone calls. It allows communications equipment and circuits, to be shared among users. Each user has sole access to a circuit (functionally equivalent to a pair of copper wires) during network use. Consider communication between two points A and D in a network. The connection between A and D is provided using (shared) links between two other pieces of equipment, B and C.

The correct answer is A collection of linked information residing on computers connected by the Internet

Important Points

World Wide Web or www is the name given to all the information available on the internet around the globe which is accessed by different devices connected to that internet.

Key Points

In 1989 the world wide web was invented by Sir Tim Berners-Lee. He was trying to find a new way for scientists to easily share the data from their experiments.
Hypertext and the internet already existed at this point but no one had thought of a way to use the internet to link one document directly to another.
Tim suggested three main technologies that meant all computers could understand each other (HTML, URL, and HTTP). All of these remain in use today.
He also made the world’s first web browser and the webserver. You can still see pages from the first web server online.

Additional Information

HTML (HyperText Markup Language) The publishing format for the web. It includes the ability to format documents and link to other documents and resources.
URL (Uniform Resource Locator) The URL is a kind of 'address' that is unique to each resource on the web. It could be the address of a webpage or an image file.
HTTP (Hypertext Transfer Protocol) Allows HTML documents to be requested and transmitted between browsers and web servers via the internet.
Web server A computer where files are stored which can be accessed via the internet using HTTP.

Key Points

The del command is a Command Prompt command used to delete files. Various command options are available so that you can remove files that have a certain file extension, delete every file in a folder, get rid of only the files with certain file attributes, and more.
Unlike deleting files normally, data removed with the del command doesn't end up in Recycle Bin.

The del command is available from within the Command Prompt in Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP operating systems.
It can also be used in Command Prompt in the Advanced Startup Options and System Recovery Options repair/recovery menus.
In Recovery Console in Windows XP and Windows 2000, the delete Recovery Console command can be used instead.

It allows prioritizing of messages.
((c))
It allows broadcasting of messages.
((d))
It is an inexpensive network.

It is not compatible with videoconferencing.

Show Answer

Answer: ((d))

It is an inexpensive network.

Message switching is a network switching technique in which data is routed in its entirety from the source node to the destination node, one hope at a time. During message routing, every intermediate switch in the network stores the whole message. If the entire network's resources are engaged or the network becomes blocked, the message-switched network stores and delays the message until ample resources become available for effective transmission of the message.

Internet data is broken up as

((a))
Fixed length packets
((b))
Variable length packets
((c))
Not packetized
((d))
64 bytes packets
((e))
None of these

Show Answer

Answer: ((b))

Variable length packets

The correct answer is Variable length packets

Important Points

The internet data has variable-length packets which signify that the length is not fixed and the packet’s length can be different though the frame length is always fixed.

Key Points

In networking, a packet is a small segment of a larger message. Data sent over computer networks, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them.
Suppose a user needs to load an image. The image file does not go from a web server to the user's computer in one piece. Instead, it is broken down into packets of data, sent over the wires, cables, and radio waves of the Internet, and then reassembled by the user's computer into the original photo.
A packet header is a "label" of sorts, which provides information about the packet’s contents, origin, and destination.

Additional Information

Packet headers go at the front of each packet. Routers, switches, computers, and anything else that processes or receives a packet will see the header first. A packet can also have trailers and footers attached at the end. Like headers, these contain additional information about the packet.
IP (Internet Protocol) is a network layer protocol that has to do with routing. It is used to make sure packets arrive at the correct destination.
"Datagram" is a segment of data sent over a packet-switched network. A datagram contains enough information to be routed from its source to its destination. By this definition, an IP packet is one example of a datagram. Essentially, the datagram is an alternative term for "packet."

((d))
4
((e))
No error

Show Answer

Answer: ((a))

The correct answer is option 1, i.e. 1.

In the first part of the sentence, the word ‘had’ (past tense) is grammatically incorrect and must be replaced with ‘has’.

From the sentence, it is evident that it is in the present tense (hint: claims (present tense)). Thus, ‘had’ must also be replaced with ‘has’ to make the sentence grammatically and contextually correct.

Hence, the sentence can be corrected as,

Japanese multinational Sony has unveiled the IMX586 stacked CMOS image sensor for smartphones, which it claims has the world's highest pixel count with 48 megapixels.

Show Answer

Answer: ((b))

The correct answer is option 2, i.e. 2.

The error is in the second part of the sentence where the word ‘who’ is incorrect and must be replaced with the word ‘which’.

‘Who’ is generally used with living beings and from the sentence we understand that reference has been made to ‘the startup’, i.e. non-living. Thus, ‘who’ must be replaced with ‘which’.

Hence, the sentence can be corrected as,

Alibaba, the startup**, which** already counts Ant Financial Services as an investor, is expected to close the next round of funding within weeks.

((c))

((d))

((e))
No error

Show Answer

Answer: ((a))

The correct answer is option 1, i.e. 1.

The error is in the first part of the sentence, where the word ‘ran’ is grammatically incorrect and must be replaced with the word ‘run’.

‘Ran’ is the past tense of ‘run’ and is used incorrectly in the sentence as the medical college is still running.

Moreover, the sentence is in the present tense, thus 'run' must be used instead of 'ran'.

Hence, the sentence can be corrected as,

The state-run Nalanda Medical College and Hospital in Bihar's Patna was severely waterlogged after heavy rainfall in the city, with fish seen swimming in the ICU on Sunday.

The correct answer is option 2, i.e. 2.

The error is in the second part of the sentence where the ‘had been’ is grammatically incorrect as the sentence is in the present tense.

The Championship will be held in October for which Kapil Dev has been selected in the national golf team.

Hence, the sentence can be corrected as,

((e))
No error

Show Answer

Answer: ((b))

The correct answer is option 2, i.e. 2.

The error is in the second part of the sentence where the use of 'struck' is incorrect.

'Struck' is the past participle of the verb 'strike' which means 'to hit forcibly and deliberately with one's hand or a weapon or other implement'.

The sentence clearly means to say that it has got 'stuck'. 'Stuck' is the past participle of 'stick' which means 'to be fixed in a particular position or unable to move or be moved'.

Hence, the sentence can be corrected as,

A man named Timothy Buchanan from California has claimed that a real-life spider has got stuck between his iMac's glass display and the screen. He suspected that the spider must have reached the monitor after crawling in through the vents on the back of the computer.

Show Answer

Answer: ((a))

The correct answer is option 1, i.e. 1.

In the above sentence, the first part of the sentence is incorrect where ‘payment’s’ is incorrect and must be replaced with ‘payments’.

As reference has been made to several payments and not just a single payment, thus, apostrophe before ‘s’ should be removed.

Hence, the sentence can be corrected as,

Digital payments major Paytm's parent company One97 Communications is planning to build a new campus in Noida's Sector 137 that will serve as Paytm's headquarters. Spread across 10 acres, the new campus is expected to house more than 15,000 employees.

Show Answer

Answer: ((c))

The correct answer is option 3, i.e. 3.

The error is in the third part of the sentence where ‘function’ is incorrect and must be replaced with ‘functions’.

‘Function’ has been used to refer to the functions of the Office of Planetary Protection (reference has been made to all the functions of the organisation) thus, ‘functions’ must be used.

Hence, the sentence can be corrected as,

American space agency NASA, that was founded on July 29, 1958, has an Office of Planetary Protection that functions to 'protect Earth's biosphere in case life does exist elsewhere'.

Read the passage carefully and answer the questions that follow. Some words may be highlighted for your attention.

For big brands, the difference can be staggering. When Mercedes-Benz shared a post on Facebook recently about the premiere of its new A-Class, the update quickly garnered more than 10,000 Likes. Impressive … until you consider that the very same image on Instagram generated more than 150,000 Likes—15 times the response! Granted, Mercedes is a visual brand and Instagram is a visual platform. (And engagement isn’t everything—Facebook, the world’s most popular social network, still enjoys an important edge in overall reach.) But the luxury automaker isn’t the only company seeing eye-popping results on Instagram. The photo-based network added 100 million users in just 5 months —rivalling Facebook’s growth numbers—and now boasts 800 million monthly users. With an audience that skews young (a majority of users reported to be under 30) and is also fiercely brand conscious (53% of users follow brands), Instagram is quietly emerging as the new home for companies seeking an impact on social media.

The dust has yet to settle on the impact of Facebook’s big decision in January to revamp its news feed—prioritising 'meaningful interactions,' especially updates from friends and family while limiting content from brands and publishers. But, for companies, it’s likely to only accelerate a shift of resources and awareness to Facebook’s younger sibling. For businesses seeking to stay ahead of the social curve, here’s why doubling down on Instagram makes sense this year.

Instagram is a skilled omnivore when it comes to devouring other networks’ features. A social network with nearly a billion users isn’t supposed to be innovative and turn-on-a-dime adaptable. But Instagram has shown itself to be just that. The 'Stories' concept, a daily disappearing montage of users’ photos and videos, may have originated with Snapchat, but Instagram has taken it mainstream since copying it 2016- adding more than 300 million users in the process.

Instagram has also been quick to embrace everything from live video and private messaging functionality to Snapchat-inspired 'filters' for creative selfies. Plus, despite some initial user resistance, the network has pivoted in recent years from a chronological stream to an algorithmic news feed—a la Facebook—giving developers and advertisers more fine-grained control over what users see. What does all of this mean for companies? Instagram’s ability to continually reinvent itself promises to pay off in the form of sustained user growth going forward.

Engagement for brands on Instagram is unparalleled. The differential comes down to Instagram’s DNA: The network is and has always been a visual-first platform. Facebook, with its 2 billion-plus users, is obviously the undisputed champion of 'reach' in the social media universe. But Instagram holds the title for an arguably more critical metric—'engagement.' While definitions vary, engagement embraces the degree to which users actually interact with content—liking, sharing and commenting, rather than just passively looking. A recent study showed that brands are getting three times more engagement on Instagram when compared apples-to-apples with Facebook. On Twitter, meanwhile, engagement rates can be less than 1/30th what they are on Instagram.

((e))

Show Answer

Answer: ((b))

2300

Given:

Percentage of people who decided to vote for X = 76%

Number of votes X got in actual = 1518

Increase in percentage of votes of Y during election = 25%

Percentage of people who did not vote = 11.11% of the number of votes by which X won

Calculation:

Let X got x votes and Y got y number of votes respectively.

Percentage of votes expected for X = 76%

Percentage of votes expected for Y = 24%

The percentage of votes obtained by Y during the election = (125/100) × 24% = 30%

Let the percentage of people who do not vote be z%

⇒ Votes X got = (70 - z)% = 1518

Number of votes by which X won = votes obtained by X - votes obtained by Y = [(70 - z) - 30]

According to question,

⇒ z = [(70 - z) - 30] × 11.11%

⇒ 9z = 40 - z

⇒ z = 4%

⇒ Votes X got, (70 - 4)% = 1518

⇒ Total votes = 2300

∴ Total votes is 2300

((b))
25.78 litres
((c))
23.4 litres
((d))
20.2 litres
((e))
None of the above

Show Answer

Answer: ((c))

23.4 litres

Pure milk = Rs. 26 per litre

SP of mixture = Rs. 26 per litre

CP of mixture = $\frac{{100}}{{130}} \times 26 = Rs.;20$ per litre

6 ∶ 20

3 ∶ 10

Milk ∶ Water = 10 ∶ 3

Bought milk worth Rs. 2,028 = $\frac{{2028}}{{26}} = 78$ litres

Amount of milk = 78 litres

Amount of water = x

78 ∶ x = 10 ∶ 3

∴ (78)(3) = 10x

∴ x = 23.4 litres

A man runs his own transportation business. He owns 3 auto-rickshaws, 4 cars and a truck. On each ride of an auto-rickshaw, he earns a profit of Rs. 20. Similarly, on each ride of a car, the profit earned is Rs. 40. A profit of Rs. 110 is earned on each ride by the truck. In the month of April 2018, each auto-rickshaw took equal number of rides on all the days of the month. Similarly, the number of rides taken by each car was also same on each day of the month. While, the number of rides taken by an auto-rickshaw and a car in the month of April is in the ratio 3 ∶ 2. At the end of the month, the man earned a total profit of Rs. 436200 from all the three types of vehicles, out of which a profit of Rs. 46200 was earned by the truck alone.

Auto-rickshaw	3	20	3x
Car	4	40	2x
Truck	1	110		46200
				436200

Ratio of rides taken by an auto-rickshaw and a car in the month = 3 ∶ 2

Let no. of rides taken by an auto-rickshaw in the month = 3x

Let no. of rides taken by a car in the month = 2x

Now,

No. of auto-rickshaws = 3

Total no. of rides taken by 3 auto-rickshaws = 3(3x) = 9x

Profit earned by an auto-rickshaw on 1 ride = Rs. 20

Profit earned by 3 auto-rickshaws on all rides = 20 × 9x = 180x

Similarly,

No. of cars = 4

Total no. of rides taken by 4 cars = 4(2x) = 8x

Profit earned by a car on 1 ride = Rs. 40

Profit earned by 4 cars on all rides = 40 × 8x = 320x

∴ Ratio of profit earned by 3 auto-rickshaws & 4 cars = 180x ∶ 320x = 9 ∶ 16

Ratio of rides taken by an auto-rickshaw and a car in the month = 3 ∶ 2

Let no. of rides taken by an auto-rickshaw in the month = 3x

Let no. of rides taken by a car in the month = 2x

Now,

No. of auto-rickshaws = 3

Total no. of rides taken by 3 auto-rickshaws = 3(3x) = 9x

Profit earned by an auto-rickshaw on 1 ride = Rs. 20

Profit earned by 3 auto-rickshaws on all rides = 20 × 9x = 180x

Similarly,

No. of cars = 4

Total no. of rides taken by 4 cars = 4(2x) = 8x

Profit earned by a car on 1 ride = Rs. 40

Profit earned by 4 cars on all rides = 40 × 8x = 320x

Hence, total profit earned by all auto-rickshaws and cars = 180x + 320x = 500x

Now,

Total profit earned by all auto-rickshaws & cars = Total profit earned – Profit earned by truck

⇒ 500x = 436200 – 46200

⇒ x = 390000/500 = 780

∴ Total no. of rides taken by 4 cars = 8x = 8(780) = 6240

Auto-rickshaw	3	20	3x
Car	4	40	2x
Truck	1	110		46200
				436200

Profit earned by truck in 1 ride = Rs. 110

Total profit earned by truck in April = Rs. 46200

Hence, total no. of rides taken by the truck in April = 46200/110 = 420

∵ The truck took equal no. of rides on all 30 days of the month of April,

⇒ No. of rides taken each day by the truck in April = 420/30 = 14

Now,

Total profit earned by truck in May = Rs. 57970

Hence, total no. of rides taken by the truck in May = 57970/110 = 527

∵ The truck took equal no. of rides on all 31 days of the month of May,

⇒ No. of rides taken each day by the truck in May = 527/31 = 17

∴ The truck took 17 – 14 = 3 more rides per day in May as compared to April

Auto-rickshaw	3	20	3x
Car	4	40	2x
Truck	1	110		46200
				436200

Let the total number of rides taken by an auto-rickshaw in the month of May and June be ‘4x’ and ‘5x’ respectively

Profit earned by an auto-rickshaw in 1 ride in May = Profit earned in April = Rs. 20

⇒Total profit earned by the auto-rickshaw in May = 20 × 4x = 80x

∵ Profit earned in 1 ride increased by 40% in the month of June,

Profit earned by an auto-rickshaw in 1 ride in June = (100 + 40)% of 20 = 140% of 20 = Rs. 28

⇒ Total profit earned by the auto-rickshaw in June = 28 × 5x = 140x

Now,

Increase in total profit earned = 140x – 80x = 60x

Percentage increase in profit = (60x/80x) × 100 = 75%

∴ The total profit earned by an auto-rickshaw in June is 75% more than that in May.

Similarly,

Average no. of rides taken by a car in 1 day = 45

Average no. of rides taken by 4 cars in 1 day = 4 × 45 = 180

Profit earned by the truck in 1 ride = Rs. 110

⇒ Average profit earned by the truck in 1 day = 12 × 110 = Rs. 1320

Now,

Average profit earned by all vehicles in 1 day = 3000 + 7200 + 1320 = Rs. 11520

∵ The year 2017 was not a leap year, it had 365 days,

∴ Average monthly profit earned by the man in 2017 = 11520 × 365/12 = Rs. 350400

Show Answer

Answer: ((c))

Either III or I and II

Let the cost price of the product be Rs. ‘x’

Selling price = Rs. 1620

Considering statement I,

Marked price = (100 + 35)% of x = 1.35x

Considering statement II,

Discount price = 20% of Marked price

Considering statements I and II,

Discount price = 20% of 1.35x = 0.27x

Selling price = Marked price - Discount

⇒ 1620 = 1.35x - 0.27x

⇒ x = 1620/1.08 = Rs. 1500

Considering statement III,

Profit = 8% of cost price = 0.08x

Selling price = cost price + profit

⇒ 1620 = x + 0.08x

⇒ x = 1620/1.08 = Rs. 1500

∴ The question can be answered using either statement III or statements I and II

Answer: ((b))

II and either I or III

Let the smaller and larger number be ‘x’ and ‘y’ respectively

Considering statement I,

⇒ 6x = 4 + 4y

⇒ 3x - 2y = 2 ----(1)

Considering statement II,

⇒ (1/2)x = 3 + (1/5)y

⇒ 5x - 2y = 30 ----(2)

Considering statement III,

⇒ 2y - 2x = x - 2

⇒ 3x - 2y = 2 ----(3)

Considering statements I and II,

Subtracting (1) from (2),

⇒ 5x - 2y - 3x + 2y = 30 - 2

⇒ 2x = 28

⇒ x = 28/2 = 14

Substituting in (1),

⇒ y = (42 - 2)/2 = 20

⇒ Average of numbers = (14 + 20)/2 = 17

Considering statements II and III,

Subtracting (3) from (2),

⇒ 5x - 2y - 3x + 2y = 30 - 2

⇒ 2x = 28

⇒ x = 28/2 = 14

Substituting in (3),

⇒ y = (42 - 2)/2 = 20

⇒ Average of numbers = (14 + 20)/2 = 17

∴ The question can be answered using statement II and either statement I or III

In statement III, the Difference mentioned needs to be positive and we can clear that confusion as we already established the smaller and larger number as ‘x’ and ‘y’ respectively.

So, Difference = (y -x) not ( x-y).

Show Answer

Answer: ((b))

40 - 28%

From the graph,

Total income of family P = Rs. 30000

Savings of family P = Rs. 30000 – (12000 + 6000) = Rs. 12000

So, percentage savings = [(12000/30000) × 100]% = 40%

Total income of family W = Rs. 25000

Savings of family W = Rs. 25000 – (10000 + 8000) = Rs. 7000

So, percentage savings = [(7000/25000) × 100]% = 28%

∴ The percentage point difference between the percentage savings of P and W = 40 – 28%.

((c))
186.9%
((d))
159.8%
((e))
159.9%

Show Answer

Answer: ((a))

173.8%

Let the cost price be Rs. 100

⇒ ∵ Profit is 15%. So, SP = Rs. 115

⇒ This SP = Rs. 115 is arrived after giving discount of 30%.

ie. Marked Price = 115/0.7 = Rs. 164.28

⇒ Now, he is selling 20 apples to a dozen. So, his loss in this case will be

= {(20 – 12) /20} × 100

= 40%

⇒ It means Rs. 164.28 were arrived after losing 40%. Hence the actual MP is

= 164.28/0.60

= Rs. 273.8

∴ Hence he has marked the MP 173.8% above CP

Answer: ((a))

6666.67

Let assume part of 10,000 put under the interest rate of 8% = x

Part of 10,000 put under the interest rate of 12% = y,

x + y = 10,000

For part x,

Interest = PRT/100,

Where, P = Rs. x,

R = 8%,

T = 3 year

Interest = (x × 8 × 3)/100 = 0.24x ---- (1)

For part y,

Interest = PRT/100,

Where, P = Rs. y

R = 12%,

T = 1 year

Interest = (y × 12 × 1)/100 = 0.12y ---- (2)

Comparing both equation,

⇒ 0.24x = 0.12y

⇒ x/y = 0.12/0.24

⇒ x/y = 1/2

⇒ 2x = y ---- (3)

Substitute the value of Eq(3),

⇒ x + 2x = 10000

⇒ 3x = 10000

⇒ x = Rs.3333.33

Put the value of x in Eq(3);

⇒ 2(3333.33) = y

∴ y = Rs. 6666.67

Answer: ((d))

6400 m

Given Length = (7/3) × Breadth

⇒ Length : Breadth = 7 : 3

Let length = 7x km, Breadth = 3x km

Distance travelled by the person at a speed of 24 kmph in 16 minutes = Perimeter of the rectangular plot

⇒ 2 × (7x + 3x)

⇒ 2 × 10x

⇒ 20x

Distance travelled by the person at a speed of 24 kmph in 16 minutes = 20x

⇒ 24 × (16/60) = 20x

⇒ (24 × 16)/(20 × 60) = x

⇒ x = (8/25) km

⇒ x = (8/25) × 1000 m

⇒ x = 320 m

⇒ Perimeter of the rectangular plot = 20 × 320 = 6400m

∴ Required Perimeter = 6400 m

Show Answer

Answer: ((c))

20%

Ratio of the number of emails read on Monday and Thursday = 19 ∶ 18

Let the number of emails read on Monday and Thursday be ‘19x’ and ‘18x’ respectively

Let the percentage of read emails that were replied on Monday be ‘y%’

Hence,

Number of replied emails on Monday = y% of 19x = 19xy/100

Percentage of read emails that were replied on Thursday = 25%

Number of replied emails on Thursday = 25% of 18x = 1/4 × 18x = 9x/2

Now,

Ratio of replied emails on Monday and Thursday = 38 ∶ 45

⇒ (19xy/100) ∶ (9x/2) = 38 ∶ 45

⇒ 19xy/100 × 2/9x = 38/45

⇒ 19y/450 = 38/45

⇒ y = 450/19 × 38/45 = 20%

∴ 20% of the read emails were replied on Monday

Show Answer

Answer: ((c))

Total number of emails received on Tuesday = 493

No. of spam emails received on Tuesday = 53

No. of emails read on Tuesday = 493 – 53 = 440

Percentage of read emails that were replied = 30%

No. of replied emails on Tuesday = 30% of 440 = 132

Let ‘x’ emails were replied on Wednesday

Total no. of emails replied on Tuesday and Wednesday = 132 + x

Also, total no. of emails received on Wednesday = 542

Total no. of emails received on Tuesday and Wednesday = 493 + 542 = 1035

Now,

Total no. of emails replied on Tuesday and Wednesday is 3 more than 20% of the total no. of emails received in Tuesday and Wednesday,

⇒ 132 + x = 3 + 20% of 1035

⇒ 132 + x = 3 + 207

⇒ x = 210 – 132 = 78

Number of emails replied on Wednesday = 78

∴ Required difference = 132 – 78 = 54

Show Answer

Answer: ((c))

125%

Total no. of spam emails received in 5 weekdays = 48 + 53 + 22 + 40 + 17 = 180

∵ Total no. of emails received on Thursday is 4 more than 220% of the total spam emails received in the five weekdays

Total no. of emails received on Thursday = 4 + 220% of 180 = 4 + 396 = 400

Now,

No. of spam emails received on Thursday = 40

No. of emails read on Thursday = 400 – 40 = 360

Percentage of read emails that were replied on Thursday = 25%

No. of replied emails on Thursday = 25% of 360 = 90

Difference between the no. of replied emails and spam emails on Thursday = 90 – 40 = 50

∴The number of emails that were replied on Thursday is = (50/40) × 100 = 125% more than the number of spam emails received on Thursday

Show Answer

Answer: ((e))

25%

Let the percentage of read emails that were replied on Friday be ‘x%’

Total number of emails received on Friday = 465

No. of spam emails received on Friday = 17

No. of emails read on Friday = 465 – 17 = 448

No. of replied emails on Friday = x% of 448

No. of read emails that were not replied on Friday = 448 – x% of 448 = (100 – x)% of 448

Similarly,

Total number of emails received on Tuesday = 493

No. of spam emails received on Tuesday = 53

No. of emails read on Tuesday = 493 – 53 = 440

Percentage of read emails that were replied = 30%

No. of replied emails on Tuesday = 30% of 440 = 132

No. of read emails that were not replied on Tuesday = 440 – 132 = 308

Now,

Ratio of not replied emails on Friday and Tuesday = 12 ∶ 11

⇒ [(100 – x)% of 448]/308 = 12/11

⇒ (100 – x)/100 = 12/11 × 308/448

⇒ 100 – x = 100 × 3/4

⇒ 100 – x = 75

⇒ x = 100 – 75 = 25%

∴ 25% of the read emails were replied on Friday

4%
((b))
5%
((c))

((e))
12%

Show Answer

Answer: ((d))

10%

Let the total number of emails received on Saturday be ‘x’

No. of emails read on Saturday = 90% of x = 0.9x

No. of replied emails on Saturday = 10% of 0.9x = 0.09x

But, only 18 emails were replied on Saturday

⇒ 0.09x = 18

⇒ x = 18/0.09 = 200

No. of emails read on Saturday = 0.9x = 0.9 × 200 = 180

No. of spam emails received on Saturday = 200 – 180 = 20

Now,

Total no. of spam emails received in six days = 48 + 53 + 22 + 40 + 17 + 20 = 200

∴ Percentage of spam emails on Saturday = 20/200 × 100 = 10%

A man borrowed Rs.80000 at a simple interest of 5% per annum. After 5 years, he deposited an amount of Rs.50000, and the interest on the remaining amount was computed at a rate of 10% per annum compounded annually. After 2 years, he was given a rebate and he cleared his debt by paying Rs.55000. How much money was rebated?

((a))
Rs.4000
((b))
Rs.5000
((c))
Rs.5500
((d))
Rs.7500
((e))
Rs.8000

Show Answer

Answer: ((c))

Rs.5500

Interest for first 5 years = (80000 × 5 × 5) /100

= Rs.20000

Amount to be paid after 5 years = Rs.(80000 + 20000)

= Rs.100000

Amount remaining after 5 years = 100000 – 50000

= Rs.50000

Amount after next 2 years = 50000 × (1 + 10/100)²

= 50000 × 1.21

= Rs.60500

∴ Amount rebated = 60500 – 55000 = Rs.5500

Jose travels from the place A to place B at a certain speed. When he comes back from place B to place A, his speed is 60 miles per hour. If the average speed for the whole journey is 72 miles per hour, find his speed when he travels from the place A to B.

((a))
40 miles per hour
((b))
50 miles per hour
((c))
70 miles per hour
((d))
90 miles per hour
((e))
25.5 miles per hour

Show Answer

Answer: ((d))

90 miles per hour

Let the distance from A to B be x miles.

Total time taken = Distance/Speed = 2x/72 = x/36 hr

Time while coming back = x/60

∴ Time taken while going from A to B = (x/36) - (x/60) = x/90

∴ Speed while going from A to B = Distance/Time = x/(x/90) = 90 miles per hour

((b))
50/7 km/hr
((c))
50/9 km/hr
((d))
100/21 km/hr
((e))
100/27 km/hr

Show Answer

Answer: ((d))

100/21 km/hr

Let the downstream speed and upstream speed be ‘a’ km/hr and ‘b’ km/hr respectively

Now, time taken to travel 20 km downstream & 10 km upstream = 2 hrs. 36 min.

⇒ 20/a + 10/b = 2.6

⇒ 10a + 20b = 2.6ab

⇒ 10a = b(2.6a – 20)

⇒ b = 10a/(2.6a – 20) ----(1)

Also, time taken to travel 10 km downstream & 20 km upstream = 3 hrs. 24 min.

⇒ 10/a + 20/b = 3.4

⇒ 20a + 10b = 3.4ab

⇒ 20a = b(3.4a – 10)

⇒ b = 20a/(3.4a – 10) ----(2)

Equating (1) and (2),

⇒ 10a/(2.6a – 20) = 20a/(3.4a – 10)

⇒ 3.4a – 10 = 2(2.6a – 20)

⇒ 3.4a – 10 = 5.2a – 40

⇒ 1.8a = 30

⇒ a = 50/3 km/hr

Substituting in (1),

⇒ b = (500/3)/(130/3 – 20) = 50/7 km/hr

∴ Speed of stream = 1/2 × (Downstream speed – Upstream speed)

= (50/3 – 50/7)/2 = 100/21 km/hr

The distance between the two points A and B is 1500 km. One train starts from point A and another from point B at the same time. If the two trains move in opposite direction, they meet in 10 hours. If they move in the same direction, they meet in 25 hours. What is the ratio of the speeds of the two trains?

((a))

((b))
2 : 7
((c))
2 : 3
((d))
7 : 2
((e))
4 : 3

Show Answer

Answer: ((a))

7 : 3

Let x kmph and y kmph be the speeds of trains starting from point A and B respectively.

When the trains move towards each other, $x + y = \frac{{1500}}{{10}}$

⇒ x + y = 150 ----(1)

When the trains move in same direction, $x - y = \frac{{1500}}{{25}}$

⇒ x - y = 60 ----(2)

On solving equation 1 and 2, we get x = 105 kmph and y = 45 kmph.

Ratio of the speeds of two train = 105 : 45 = 7 : 3

In a certain number of days, 10 workers were assigned to complete a task. Since some of the workers have not worked all these days, only 25% of the task was completed after 15 days. From the 16^th day onwards when all 10 started working, the percentage of the total work that was completed at the end of the assigned days was 62.5%. How many days were assigned initially?

((a))
20
((b))
22
((c))
24
((d))
25
((e))
None of these

Show Answer

Answer: ((c))

Let the number of days taken by the 10 workers to complete the task be x days

The fraction of work done in one day = (1/10x)

From the 16^th to the xth day, 10 workers worked and completed (62.5 - 25) = 37.5% of the work

⇒ (1/10x) × (x - 15) × 10 = (37.5/100)

⇒ (x - 15)/x = 37.5/100

⇒ (x - 15)/x = 3/8

⇒ (x - 15) × 8 = x × 3

⇒ 8x - 120 = 3x

⇒ 5x = 120

⇒ x = 120/5 = 24

∴ Number of days assigned initially = 24

Show Answer

Answer: ((c))

1 hr. 24 min.

GIVEN :

Pipes A & B can together fill a tank in 4 hours.

C & D can empty the tank in 10 hours and 12 hours respectively.

CALCULATION :

Part filled by pipes A & B in 1 hr = 1/4

Part emptied by pipe C in 1 hr = 1/10

Part emptied by pipe D in 1 hr = 1/12

Now, pipe A & B were open for = 3 hours

Pipe C was open for = 3 - 1 = 2 hours

Let pipe D was opened after ‘x’ hours of opening of pipe C,

Pipe D was open for = (2 - x) hours

Hence, part filled in 3 hours = 1/2

⇒ Part filled by A & B - Part emptied by C & D = 1/2

⇒ 3 × (1/4) - 2 × (1/10) - (2 - x) × (1/12) = 1/2

⇒ 3/4 - 1/5 - (2 - x)/12 = 1/2

⇒ 45 - 12 - 10 + 5x = 30

⇒ 5x = 7

⇒ x = 7/5 = 1.4 hrs = 1 hr. 24 min.

∴ Pipe D was opened after 1 hr. 24 min. of opening of pipe C

Answer: ((e))

15488

There are 32 black and 32 white squares on a chess board. Then the number of ways in choosing 2 white squares and 1 black square are :

³²C₂ × ³²C₁ = 15872

Number of ways in which all squares lie on the same row : ⁴C₂× ⁴C₁ × 8 = 192

Number of ways in which all squares lie on the same column : ⁴C₂× ⁴C₁ × 8 = 192

Total number of ways in which all squares lie on the same row or column = 192 × 2 = 384

Required number of ways

⇒ 15872 – 384 = 15488

Answer: ((b))

$\frac{1}{7}$

GIVEN :

In a bag there are 5 red balls, 6 blue balls and 7 white balls.

If the first ball turns out to be of blue colour, then 4 more blue coloured balls are to be added to the bag.

CALCULATION :

Let the probability of first ball to be drawn is blue is = $\frac{6}{{18}} = \frac{1}{3}$

And if the second ball drawn is also blue then according to question no of blue balls become = 5 + 4 = 9

So, probability of second ball to be blue is $= \frac{9}{{21}} = \frac{3}{7}$

∴ Probability of both balls to be blue = $\frac{1}{3} \times \frac{3}{7} = \frac{1}{7}$
