Subject: Chaotic traffic in the area

Respected Sir,

This letter intends to bring to your kind attention the unimaginable harassment that the people are facing around my school, due to the growing instances of traffic jams. We know that the number of vehicles on the roads is on the rise and that there is no proportional increase in the number of roads. So, traffic jams are bound to happen. But I do not intend to disturb you with things that do not have an immediate solution.

It stretches one’s tolerance to the ultimate limit when a difficult situation is aggravated due to the irresponsible behaviour of a few rogue drivers. The Buses and autos on this busy road show an appalling disregard for any kind of traffic law. Buses stopping here and there, autos coming and going through and into every corner and side of the traffic imaginable, drivers getting into an ugly argument on the middle of the road etc., cause havoc for the daily commuter. Also, it's a school zone, so it is even more dangerous for us students who walk in this area.

Auto drivers are presumably above the law for no police officer seems to have the courage of taking them to task because of their strong union. Please do not mind my mentioning the passivity of the police officers posted in the area. Some of the leading newspapers in the area yesterday published photographs of a police officer and a constable smoking (despite the Supreme Court ban) on the Alipore Road even while the traffic was in the doldrums. Need I say more?

It seems that the concerned officers respond to the call of duty only when some minister is using a particular road. I hope you do not construe my helplessness as rudeness.

The most difficult hours during the day are in the morning, when we go to school, and in the evening, when we are returning back home. There are a total of four schools in my area, and this makes the traffic even worse. This is due to the private vehicles that are used to drop us and pick us up from school. I suggest that measures are taken to create an awareness against the usage of private vehicles. Personally, I walk up to school because I live only five minutes away, but, the roads are more dangerous for us pedestrians as there are drivers who try to ride their scooters from every possible space available on the road as well as footpath.

I suggest that a diversion be created along the road that leads to the school, this would make the road a bit safer to walk on. I also suggest that a traffic inspector is assigned to manage the traffic, as the absence of one creates a complete chaos every day on the road.

We have faith in the Police Department and fully understand that there are some dedicated officers who are working day and night to ensure our safety in every sphere. With all due respect to them, I believe that the Police Department needs to pull up its socks to combat the menace of nuisance drivers who aggravate the problem of traffic jams in our city.

Thanking you in anticipation,

Yours sincerely,

Vinay Bora

The Green movement:   it is a diverse scientific, social, conservation, and political movement that broadly addresses the concerns of the environment. It was started in 1972. It aims at creating a holistic and ecological view of the world.

   It has become more popular because nowadays the population was increasing so, because of population people need more space and they were cutting down forests commonly as deforestation, and for those populations we need clothes, food, etc and that we industries for producing those things. For setting up those industries we need space and then we also cut the forests, then again deforestation.

The following line means that nobody owns the earth for themselves. Humans are mere tenants of the earth, and have the responsibility of looking after it and leaving it as they found it on the day they were born. 

Quality is an important factor when it comes to any product or service. ... Quality control is essential to building a successful business that delivers products that meet or exceed customers' expectations.

They also enable you to charge and maintain higher prices.

Adam Smith was an 18th-century Scottish economist, philosopher, and author, and is considered the father of modern economics. However, Samuelson became the first American to win the Nobel Prize in Economics (1970) for his work to transform the fundamental nature of the discipline.

“There was an arduous journey ahead but it was time to let the whole world know loud and clear that India was wide awake. The rest is history. Looking back, Narasimha Rao can truly be called the father of economic reforms in India,” the former prime minister said.

Let the length and breadth of the park be l and b.
Perimeter = 2 (l + b) = 80
l + b = 40
Or, b = 40 - l
Area = l×b = l(40 - l) = 40l - l240l -  l2 = 400
l2 -  40l + 400 = 0
Comparing this equation with al2 + bl + c = 0, we get
a = 1, b = -40, c = 400
Discriminant = b2 - 4ac
(-40)2 - 4 × 400
= 1600 - 1600 = 0
b2 - 4ac = 0
Therefore, this equation has equal real roots. And hence, this situation is possible.
Root of this equation,l = -b/2a
l = (40)/2(1) = 40/2 = 20
Therefore, length of park, l = 20 m
And breadth of park, b = 40 - l = 40 - 20 = 20 m.

A tribe is a group of people living under primitive condition and still not popularly known to more modern culture. There are numbers of tribes living all over India as well as various parts in the World. More than 55% of the total tribal population of India are living in central India like Bihar, West Bengal, Orissa, and Madhya Pradesh and remaining tribal population is concentrated in the Himalayan belt, Western India, the Dravidian region and Andaman, Nicobar and Lakshadweep islands. According to D.N Majumdar, tribes as social group with popular association endogamous with not any particular of functions governed by tribal ruler or otherwise, united in language or dialect recognizing social distance with other tribes or castes. Out of them, Santhal is an important tribe which contributes more than 50% of the Indian tribal population. The paper tries to explain heartening situation of Indian tribes with reference to Santhal communities in Birbhum district and also finds out various cultural as well as food habits, religious practices, social system like marriage and various types of awareness. Social change is one of the important issues which can determined the level of development and change in the pattern of life style. L.M Lewis believes that tribal societies are small in scale are restricted in the spatial and temporal range of their social, legal and political relations and possess a morality, a religion and world view of corresponding dimensions.

-2/3 × 3/5 + 5/2 - 3/5 ×1/5

= -2/5 +5/2 - 3/25

= (-20 + 125- 6)/50

= 99/50

It is composed of the following constituents:

• Phospholipids – forms the ultimate fabric of the membrane
• Peripheral proteins – present on the outer or inner surface of phospholipid bilayer but are not implanted in the hydrophobic core
• Cholesterol – folded between the hydrophobic tails of phospholipid membrane
• Carbohydrates – found to be attached to the lipids or proteins on the extracellular side of the membrane, leading to the formation of glycolipids and glycoproteins
• Integral proteins – found to be implanted in the phospholipid bilayer

2. Mantle: It is the layer that lies below the crust. The thickness of mantle is 2,900 kilometres.
3. Core: It is the innermost layer of the Earth  and is 3,500-kilometres thick.

When a new stamp is issued, the stamp collectors buy that stamp and use them to the envelops on the very first day of the sale. The new stamp gets the post mark and the date. This is called the “first day cover”. The receiver never opens it because he knows that he has himself just put a blank paper in it. Charley found this type of cover in his stamp-collection.
