Given:

Five years ago, father's age was 5 times that of his son

After 3 years father will be 3 times as old as his son

Calculation:

Let the present age of son be x years 

Present age of father be y years 

According to the question,

Five years ago, father's age was 5 times that of his son

(y - 5) = 5 (x - 5)

⇒ y - 5 = 5x - 25 

⇒ y - 5x + 20 = 0     ---- (i)

After 3 years father will be 3 times as old as his son

(y + 3) = 3(x + 3)

⇒ y + 3 = 3x + 9

⇒ y - 3x - 6 = 0      ---- (ii)

Solving equation (i) and (ii) we get,

x = 13

∴ Present age of son is 13 years

Thus, the code for REMAIN is 8@7$%6.

Let the first part = x
Second part = y
30% of y – 75% of x = 12 ----(1)
50% of y – 80% of x = 56 ----(2)
0.60 × Eq₂ – Eq₁
75% of x – 48% of x = 0.60 × 56 – 12
27% of x = 21.60

30% of y – 75% of 80 = 12
30% of y = 72
y = 240
so number is there sum ie. x + y
So the answer = 80 + 240 = 320
Hence, Option B is correct.

First, find the normal rate of Pipe A:

• Pipe A fills 1000 liters in 150 minutes.
• Hence, its normal rate = 1000 / 150 = 6.6667 liters per minute.

Next, if it works at only 5% efficiency, its rate becomes:

• 5% of 6.6667 = 0.05 × 6.6667 = 0.3333 liters per minute (approximately).

Finally, to fill 60 liters at this reduced rate:

• Time required = 60 / 0.3333 ≈ 180 minutes.

Answer: 180 minutes (Option c).

Hence, Option C is correct.

2.31312345…as it has a non terminating non repeating decimal form.

Volume of the cylinder = πr²h = 1232


Hence, Option A is correct.

Hence, Option C is correct.

The 91st Interpol General Assembly, led by the Indian delegation comprising the Central Bureau of Investigation (CBI) and National Investigation Agency (NIA), emphasized denying safe havens to crime. It took place in Vienna, Austria.

When the quantity of acids in the raining water is more than the average, then such rain is called 'Acid rain'.

We are aware that normally rainwater has a pH of 5.6.  When the pH of the rainwater drops below 5.6, it is called acid rain.

Acid rain refers to the ways in which acid from the atmosphere is deposited on the earth’s surface. Oxides of nitrogen and sulphur which are acidic in nature can be blown by the wind along with solid particles in the atmosphere and finally settle down either on the ground as dry deposition or in water, fog and snow as wet deposition.

∴ The average pH value of the acid rain is 4 to 5 and hence the average value of 4.5.

The bad effects of acid rain

• When acid rain falls and flows as groundwater to reach rivers, lakes etc, it affects plants and animal life in the aquatic ecosystem
• Acid rain is harmful to agriculture, trees and plants as it dissolves and washes away nutrients needed for their growth
• It causes respiratory ailments in human beings and animal
• It may also cause corrosion in many buildings bridges, monuments, fencing etc
• It causes irritation in the eyes and skin of human beings
• This rain reduces the lustre of the metals too
• Acid rain damages buildings and other structures made of stone or metal
• The Taj Mahal in India has been affected by acid rain

The United Front government was indeed supported by the Congress party from the outside. The Fodder Scam in Bihar involved Lalu Prasad Yadav, leading to his resignation from his party and the formation of the Rashtriya Janata Dal.

The 73rd Constitutional Amendment provided constitutional recognition and structure to the Panchayati Raj institutions, enhancing local self-governance.

The assertion is incorrect because the Government of India Act, 1919, introduced responsible government only at the provincial level, not at the central level. The reason is correct in stating that the act introduced Dyarchy as a step towards more self-governing institutions in India, but it did not establish responsible government at the central level.

The electrostatic precipitator is one of the most widely used collection devices for particulates. An electrostatic precipitator (ESP) is a particulate collection device that removes particles from a flowing gaseous stream (such as air) using the force of an induced electrostatic charge.

ESP can be operated at high temperatures and pressures, and its power requirement is low. An electrostatic precipitator is a type of filter (dry scrubber) that uses static electricity to remove soot and ash from exhaust fumes before they exit the smokestacks. 

∴ An electrostatic precipitator is a device to control particulate emissions only.

Noise:

• Noise is defined as unwanted sound which is considered unpleasant, loud, and disruptive to hearing.
• It is indistinguisable from sound as both are vibrabations through a medium, such as air or water.
• The difference rises, when the brain recieves and percievs it.
• Minimum(Faintest) sound level which is audible for humans is 1 dB
• Threshold of discomfort for humans = 110 dB
• Threshold for pain for humans = 140 dB

Additional Information

Permissble noise levels:

• The partition that was officially announced was that the Bengal province was too large to be administered by a single governor and so it would be partitioned on administrative purpose.

•  

  The real reason behind the partition was political and not administrative. East Bengal was dominated by the Muslims and West Bengal by the Hindus. Partition was yet another part of the divide and rule policy.

Noise pollution may cause or contribute to the following adverse effects:

• Anxiety, stress, nervousness, nausea, headache
• Emotional instability
• Hypertension
• Hearing loss
• Argumentativeness
• Increase in social conflicts

• Insomnia as a result of lack of undisturbed and refreshing sleep

The correct answer is Biosphere.

Concept:

Ecosystem:  

• It is a community or group of living organisms that live in and interact with each other in a specific environment.
• for eg: Tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and microorganisms that are in constant interaction between themselves and the physical (sun, temperature) or chemical (oxygen or nutrients) components.

Explanations:

• The ecosystem is the smallest unit of the Biosphere.
• The earth environment contains four components namely Lithosphere, Biosphere, Hydrosphere and Atmosphere.
• As the biosphere is comprised of a group of ecosystems linked together, hence ecosystem is considered as the "smallest unit of the biosphere.

Additional Information

• The Biosphere and Lithosphere are the components of the environment whereas the Mesosphere and Ionosphere are two of the layers of the Atmosphere.
