Correct answer

Answer: (a)A.

C

Why this answer is correct

Explanation:

We know,

For a Rectangle, the adjacent sides will be perpendicular to each other (∵ Angle between them = 90° )

For a Rhombus, the two diagonals will be perpendicular to each other (∵ Angle between them = 90° )

For a Square, the adjacent sides will be perpendicular to  each other (∵ Angle between them = 90° )

But,

For a Right-angle triangle, Hypotenuse and One side will not be perpendicular to each other

∴ The odd statement is C

Note: For a Right-angle triangle, the other two sides except Hypotenuse will be perpendicular to each other

  3. COption (c)

    12

  4. DOption (d)

    15

View answer & explanation

Correct answer

Answer: (b)B.

10

Why this answer is correct

Let the number of men who agreed to do the work in 20 days be x

⇒ work done by x men = 20x

Also given (x - 5) men will complete the work in 40 days

⇒ work done by (x - 5) men = 40(x - 5)

Since the work done by both are same

⇒ 20x = 40(x - 5)

⇒ 20x - 40x = - 200

⇒ x = 10

∴ No of men who had agreed to do the work originally = 10

    Both arguments I and II are strong.

  2. BOption (b)

    Only argument II is strong.

  3. COption (c)

    Neither argument I nor II is strong.

  4. DOption (d)

    Only argument I is strong.

View answer & explanation

Correct answer

Answer: (d)D.

Only argument I is strong.

Why this answer is correct

In the 21st-century internet is expanding exponentially and contains a lot of information that should not be viewed by children. Argument I holds strong on the note that children should “know how to use the Internet responsibly”. While “exploring on their own” will definitely help them to “learn a lot”, it can mislead children and influence them in a wrong way. Thus argument II does not hold strong.

Hence “only argument I is strong”.

View answer & explanation

Correct answer

Answer: (b)B.

273

Why this answer is correct

Let the two positive numbers be x and y

From the given data,

⇒ x + y = 34       - - - - equation (1)

⇒ x - y = 8         - - - equation (2)

By adding equation (1) and equation (2), we get

⇒ 2x = 42

⇒ x = 42/2 = 21

Substitute x = 21 in equation (1)

⇒ x + y = 34

⇒ 21 + y = 34

⇒ y = 34 – 21 = 13

∴ Their product = xy = 21 × 13 = 273

Rs. 2800

Why this answer is correct

S.I = PRT/100

Here P = Principle, R = Rate T = Time, S.I = Simple interest

S. I = 5200 – 4000 = (4000 × R × 10)/100

⇒ R = (1200 × 100)/(4000 × 10) = 3%

New rate = 3 + 4 = 7%

Interest = (4000 × 7 × 10)/100 = Rs. 2800

  • Salicylic acid also called ortho-hydroxybenzoic acid, a white, crystalline solid that is used chiefly in the preparation of aspirin and other pharmaceutical products.
  • The free acid occurs naturally in small amounts in many plants.
  • Salicylic acid is a component of preparations used to combat warts, corns, calluses, and various skin diseases.

Linoleic acid:

  • Linoleic acid is a polyunsaturated omega-6 fatty acid.
  • It is a colourless or white oil that is virtually insoluble in water but very soluble in acetone, benzene, diethyl ether and ethanol.
  • It typically occurs in nature as a triglyceride (ester of glycerin) rather than as a free fatty acid.

  4. DOption (d)

    Rs. 2,750

View answer & explanation

Correct answer

Answer: (b)B.

Rs. 2,770

Why this answer is correct

From the given data,

Cost price of 10 kg of rice = 10 × 75 = Rs. 750

Cost price of 20 kg of sugar = 20 × 85 = Rs. 1700

Given that profit for rice is 20% and profit for sugar is 10%

We know that profit = Cost price × profit% /100 = 750 × 20/100 = Rs. 150

⇒ Selling Price of rice = cost price of rice + profit on rice = 150 + 750 = Rs. 900

Also for profit 10% for sugar

⇒ Profit on sugar = 1700 × 10/100 = Rs. 170

⇒ Selling Price of sugar = Cost price of sugar + profit on sugar = 1700 + 170 = Rs. 1870

∴ Total sale = SP of rice + SP of sugar = 900 + 1870 = Rs. 2770

A trader bought 10 kg of rice at Rs. 400 per kg. He sold half the quantity at 20% loss and remaining at 10% profit. What was his net profit or loss in percentage?

  1. AOption (a)

    5% loss

  2. BOption (b)

    5% gain

  3. COption (c)

    10% loss

  4. DOption (d)

    10% gain

View answer & explanation

Correct answer

Answer: (a)A.

5% loss

Why this answer is correct

Cost price of 10 kg of rice = Rs. 400 × 10 = Rs. 4000

Cost price of 5 kg of rice = Rs. 2000 and the cost price of the remaining 5 kg of rice = Rs. 2000

Also given that trader got 20% loss for half of the quantity

We know that loss% = (CP - SP)/CP × 100

⇒ 20 = (2000 - SP)/2000 × 100

⇒ 200000 - 40000 = 100SP

⇒ SP = Rs. 1600

∴ Loss for first half = 2000 - 1600 = Rs. 400

Also given that profit for second half is 10%

⇒ 10 = (SP - 2000)/2000 × 100

⇒ 100SP = 20000 + 200000

⇒ SP = 2200

 Profit for second half = 2200 - 2000 = Rs. 200

∴ Net there is a loss of Rs. 200

Final loss % = (net loss/total cost price × 100) = 200/4000 × 100 = 5%

View answer & explanation

Correct answer

Answer: (d)D.

Firewall protects computer from fire.

Why this answer is correct

The correct answer is Firewall protects the computer from fire(which is an odd statement).

  • A firewall put simply, is a barrier – a barrier between a secure and trusted internal network and that of an outside network.
  • Firewalls can be implemented in both hardware and software, or through a combination of both.

Additional Information

  • Following types of Firewalls -
  1. Packet-filtering firewall: It checks every packet that passes the firewall and examines the packet as per the set of rules that the user sets up. If the packet gets to pass the test, it’s allowed to go through. If the packet fails to pass the test then it is rejected. Packet filters are the most inexpensive variety of firewalls. That is why packet-filtering firewalls are used very commonly.
  2. Stateful packet inspection (SPI): It is installed in accordance with simple packet filtering. A firewall having Stateful packet checking looks at packets in clusters instead of doing individually. It maintains the record of all those packets have crossed through the firewall and can create patterns that indicate unauthorized entry.
  3. Deep packet inspection (DPI): It is the actual data of the packets is checked so viruses, spam, and other harmful content can be restricted. DPI also enables practices, such as data mining, eavesdropping, and content censorship, which make its way through a controversial subject.
