  1. ((a))

    122° F

  2. ((b))

    115° F

  3. ((c))

    132° F

  4. ((d))

    140° F

Show Answer
Answer: ((a))

122° F

The Correct Answer is 122° F.

Key Points

  • The formula to convert Celsius to Fahrenheit is given by 
  • C = (F - 32) × 59\frac{5}{9}
  • F = [ C × (9/5) + 32 ]
  • Given that, C = 50
  • Then, F = 50 × (9/5) + 32
  • F = 90 + 32
  • F = 122

Important Points

Concept:

  • Temperature: It is the measure of the degree of hotness and coldness of a body.
  • The SI unit of temperature is Kelvin (K).

Fahrenheit and Celsius are measurements of temperature and are related to each other as follows:

C = (F - 32) × 59\frac{5}{9}

Where C is the temperature in Celsius and F is the temperature in Fahrenheit.

EXPLANATION:

Since we need temperature in Fahrenheit and Celsius to be equal:

Now, let C = F = x

So,

x = (x - 32) × 59\frac{5}{9}

or, 9x = 5x – 160

or, 4x = -160

or, x = -40

Therefore, -40°C = -40°F

Acid rain is caused by environmental pollution caused by what?

  1. ((a))

    Carbon dioxide and Nitrogen

  2. ((b))

    Carbon monoxide and Carbon dioxide

  3. ((c))

    Ozone and Carbon dioxide

  4. ((d))

    Nitrous Oxide and Sulfur Dioxide

Show Answer
Answer: ((d))

Nitrous Oxide and Sulfur Dioxide

The Correct Answer is Nitrous Oxide and Sulfur Dioxide.

Key Points

  • Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.
  • These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
  • Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by the wind.
  • As a result, the two compounds can travel long distances where they become part of the rain, sleet, snow, and fog that we experience on certain days.
  • Human activities are the main cause of acid rain.
  • Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere.
  • Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity.
  • In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

Additional Information

  • Acid Rain is Caused by Reactions in the Environment
  • Nature depends on balance, and although some rain is naturally acidic, with a pH level of around 5.0, human activities have made it worse.
  • Normal precipitation - such as rain, sleet, or snow—reacts with alkaline chemicals, or non-acidic materials, that can be found in air, soils, bedrock, lakes, and streams.
  • These reactions usually neutralize natural acids. However, if precipitation becomes too acidic, these materials may not be able to neutralize all of the acids.
  • Over time, these neutralizing materials can be washed away by acid rain.
  • Damage to crops, trees, lakes, rivers, and animals can result.

  • The gas used in the manufacture of vegetable ghee from vegetable oil is hydrogen.
  • At high pressure, in the presence of a nickel catalyst, hydrogen is mixed with vegetable oils, ;which turns them into vegetable ghee.
  • This process is called the hydrogenation of oils.
  • Hydrogen:
  • Hydrogen is the chemical element having the symbol H and atomic number 1.
  • With a normal atomic weight of 1.008, hydrogen is the lightest element in the periodic table.
  • Hydrogen is the most copious chemical substance in the universe, constituting roughly 75% of all baryonic mass.
  • Hydrogen gas ;is used by industry for refining petroleum, treating metals, producing fertiliser, and processing foods.

Additional Information

  • Nitrogen:
  • Nitrogen (N), a nonmetallic element of Group 15 [Va] of the periodic table.
  • It is a colourless, odourless, tasteless gas that is the most plentiful element in Earth’s atmosphere and is a constituent of all living matter.
  • Elemental nitrogen can be used as an inert atmosphere for reactions requiring the exclusion of oxygen and moisture.
  • In the liquid state, nitrogen has valuable cryogenic applications; except for the gases hydrogen, methane, carbon monoxide, fluorine, and oxygen, practically all chemical substances have negligible vapour pressures at the boiling point of nitrogen and exist, therefore, as crystalline solids at that temperature.
  • Carbon dioxide:
  • Carbon dioxide, (CO2), a colourless gas with a faint, sharp odour and a sour taste.
  • It is one of the most important greenhouse gases linked to global warming, but it is a minor component of Earth’s atmosphere (about 3 volumes in 10,000), formed in the combustion of carbon-containing materials, in fermentation, and in the respiration of animals, and employed by plants in the photosynthesis of carbohydrates.
  • The presence of the gas in the atmosphere keeps some of the radiant energy received by Earth from being returned to space, thus producing the so-called greenhouse effect.
  • Industrially, it is recovered for numerous diverse applications from flue gases, as a by-product of the preparation of hydrogen for the synthesis of ammonia, from limekilns, and from other sources.
  • Carbon dioxide is used as a refrigerant, in fire extinguishers, for inflating life rafts and life jackets, blasting coal, foaming rubber and plastics, promoting the growth of plants in greenhouses, immobilising animals before slaughter, and in carbonated beverages.

  • It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat.
  • It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse.
  • Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.
  • Opium - 
  • Opium is a depressant drug, which means it slows down the messages travelling between your brain and body.
  • It is derived from the opium poppy (Papaver somniferum L.) and is one of the earliest plants recorded for medicinal use.

The Correct Answer is From Ultraviolet Rays.

Key Points

  • The ozone layer is mainly found in the stratosphere.
  • Ozone layer acts as a shield that absorbs ultraviolet radiation from the sun.
  • UV rays are highly injurious to living organisms since DNA and proteins of living organisms preferentially absorb UV rays, and its high energy breaks the chemical bonds within these molecules.
  • UV-B damages DNA and mutation may occur.
  • It causes aging of the skin, damage to skin cells and various types of skin cancers.

Additional Information

  • Infra-Red Rays - 
  • Infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption.
  • Thus, infrared energy can also reveal objects in the universe that cannot be seen in visible light using optical telescopes.
  • X-Rays -
  • X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film or digital media.
  • Standard X-rays are performed for many reasons, including diagnosing tumors or bone injuries.

  2. ((b))

    Rs 1,19,000

  3. ((c))

    Rs 1,27,000

  4. ((d))

    Rs 77,000

Show Answer
Answer: ((b))

Rs 1,19,000

Shortcut Trick

R = (7000/50000)×100 = 14%

Rate for 5 years = 14×5 = 70%

A = (70000/100)×170 = 119000

Alternate MethodGiven:

Principal amount (P) = Rs 50,000

Final amount (A) = Rs 57,000

Time (T) = 1 year

Concept:

We need to find the rate of interest (R) first. Once we have the rate, we can use it to calculate the amount after 5 years when the principal is Rs 70,000.

Formula Used:

SI = A − P

SI = (P × R × T)/100

Calculation:

SI = A − P

= 57000 − 50000 = 7,000

Solve for R,

SI = (P × R × T)/100

7000 = (50000 × R × 1)/100

R = 70/5 = 14%

Now, we have found the rate of interest (R) to be 14%.

Calculate the amount after 5 years when the principal is Rs 70000:

SI = (P × R × T)/100

SI = (70000 × 14 × 5)/100 = 49000

Amount = Principal + Interest

A = 70000 + 49000 = 119000

∴  Rs 70,000 will become Rs 119,000 after 5 years at the same rate of simple interest.

Given:

When 75 is added to 75% of a number, the result is that number itself.

Calculation:

Let the number be x.

x = 75 + 75% of x

⇒ x = 75 + 0.75 × x

⇒ x - 0.75x = 75

⇒ 0.25x = 75

⇒ x = 75 / 0.25

⇒ x = 300

Now, finding 40% of x:

40% of 300 = 0.40 × 300 = 120

∴ 40% of the number is 120.

Given:

Average age of 4 boys (5 years ago) = 9

Average of 5 boys at present = 15 years

Formula used:

Average = Sum of Observations/Number of Observations

Calculation:

Average = 9 = Total age of 4 boys / 4

Total age of 4 boys (5 years ago) = 9 × 4 = 36

Total age of 4 boys at present = 36 + (5 × 4) = 56 years

Total age of all 5 boys at present = 15 × 5 = 75

Age of 5th boy at present = Age of all 5 boys - Age of 4 boys (At present)

Age of 5th boy = 75 - 56 = 19 years

∴ The correct answer is 19 years.

Answer: ((a))

Rs. 3,800

Given:

Marked Price (MP) of the article = Rs 5,000

Discount given = 5%

Profit earned = 25%

Formula used:

SP = MP - Discount

Profit % = [(SP - CP)/CP] × 100

CP = SP × 100/(100 + P %)

Calculation:

Discount Amount = (5 / 100) × 5,000 = Rs 250 

Sale Price = Marked Price - Discount = 5,000 - 250 = Rs 4,750

Now, Profit % = 25,

CP = SP × 100/(100 + P %)

CP = 4750 × 100/(100 + 25)

4750 × 100/125 = Rs. 3800

∴ The purchase price of the item is Rs 3,800.

Show Answer
Answer: ((c))

13

Given:

The interchanged number is 18 more than the original number.

The sum of the digits is 4.

Formula used:

Let the tens digit be x and the unit digit be y.

Original number = 10x + y

Interchanged number = 10y + x

Calculation:

⇒ 10y + x = 10x + y + 18

⇒ 9y - 9x = 18

⇒ y - x = 2 ...(i)

Given the sum of the digits,

⇒ x + y = 4 ...(ii)

Adding (i) and (ii),

⇒ 2y = 6

⇒ y = 3

Using y in (ii),

⇒ x + 3 = 4

⇒ x = 1

∴ The original number is 10x + y = 10×1 + 3 = 13.

Show Answer
Answer: ((a))

Only I

Concept:

  • One-dimensional motion: Motion along a straight line or motion in one particular direction.
  • Two-dimensional motion: Two-dimensional (2D) motion means motion that takes place in two different directions (or coordinates) at the same time.
  • The simplest motion would be an object moving linearly in one dimension.
  • An example of linear movement would be a car moving along a straight road or a ball thrown straight up from the ground.

Explanation:

  • In this diagram, speed is greater than equals to zero and time is also increasing.
  • Hence, this is a correct representation of motion in one dimension.
  • In this diagram, at the same time, a particle has two positions, which is not possible.
  • In this diagram, speed is negative, which is not possible for motion in one dimension.
  • Hence, Only I is the correct answer.

  4. ((d))

    Only conclusion II follows.

Show Answer
Answer: ((c))

Only conclusion I follows.

Given: 

"Human organism grows and develops through stimulus and action."

Conclusion I:

"Inactive human organism cannot grow and develop."→ **"Follow" (**it logically follows that an inactive human organism, without those stimuli and actions, would not be able to grow and develop).

Conclusion II:

"Human organisms do not react to stimuli and action.""→ "Doesn't follow" (It is given that Human organism grows and develops through stimulus and action. So, it cannot be possible).

Therefore, only conclusion I follow.

Hence, the correct answer is "Option 1".
