To
The Chief District Medical Officer,
Cuttack
Sub: Steps to improve facilities in the hospital Sir,
I wish to invite your attention to some serious problems that the local hospital in Nigeria has been facing for some time. (The problems: inadequate staff; vacant posts not filled; unsanitary conditions; garbage dumped all around; poor maintenance of buildings and equipment; shortage of essential medicines, etc.) (Action requested: Yours faithfully, (Srinivas Sahu)

Answer:

Nua Patna Gram Panchayat
Tigiria, Cuttack
14, March, 20

To
The Chief District Medical Officer
Cuttack
Sir,
I wish to invite your attention to some serious problems that the local hospital at Tigiria has been facing for some time. First of all, Tigiria has been plagued by a lack of adequate staff for the last five years. While the sanctioned strength of doctors is twelve, there are only two of them. Moreover, the two doctors now posted at Tigiria are only graduates. There is no one to man the different other departments established at the hospital’s foundation by the WHO.

One is tempted to ask what has happened to the funds/grants that are being sanctioned every year by the W.H.O. in lieu of the salary of doctors. Similarly, where there ought to be 20 nurses there are only 6; of 8 pharmacists only 2, and of 10 attendants only 1. With such a skeletal staff one wonders how such a large hospital with such a great inflow of patients, can be run.

Secondly, there is the unsanitary condition of the hospital. Wards are being cleaned only once a week. Sweepers complain about the non-availability of phenyl, bleaching powder, and other disinfectants. As a result, the environs of the hospital emit a foul smell. This is compounded by the garbage piled behind the hospital. Without an incinerator or some kind of waste disposal unit, the hospital is becoming a breeding ground for germs and viruses from which it is intended to protect people.

Thirdly, poor maintenance of buildings and equipment is having its toll on patients. The air-conditioner in the ICU is ‘under repair’ for the last year. The x-ray machine is out of order and so on. One does not know when the leaking wards will be repaired and how long it will be before the hospital is whitewashed. Finally, what is of great concern is the shortage of essential medicines.

Oral rehydration packets, Enteroquinol, Quinine, Primaquin, etc. are always in short supply thereby resulting in a number of deaths. I request you therefore to kindly visit the hospital and get a first-hand experience of the situation here. I would also request you ensure the supply of essential medicines immediately so that common deaths from dysentery and malaria do not recur. Doctors, nurses, and pharmacists may also be transferred from overstaffed city hospitals.
Yours faithfully,
(Srinivas Sahu)

Your friend wants to send a letter to the Chairman of the Municipality complaining about the neglect of roads and drains in your locality. As he is going out, he expects you to write a letter to him. He gives you the following points. Write a letter to him.

From
Mr. Sujit Mishra
Ward Member, Municipal Council
Sector – 3, Rourkela
Date – 20 Feb, 20
To
The Chairman Rourkela Municipality
Rourkela
Sub: Improvement of civil facilities.
Sir,
– neglect of roads and drains
– roads not swept
– piles of garbage
– drains blocked
– stagnant water
– mosquitoes and flies
– place unhygienic
– request to clean the roads and drains twice every week
Yours faithfully,
(Sujit Mishra)

Answer:

Sector – 3
Rourkela
20, February, 20

To
The Chairman
Rourkela Municipality
Rourkela
Sir,
I would like to draw your attention to the unsanitary conditions that plague our locality. There is complete neglect of roads and drains in our sector. The roads are seldom swept and piles of garbage can be seen at every comer. Moreover, as some of the garbage has been washed into the drains by the rains, the drains have been completely blocked.

As a result, there is at least two feet of standing water in the drain. This has thus become a suitable place for the breeding of mosquitoes and flies, thereby making the whole locality unhygienic. I request you therefore to kindly see that the roads and drains are cleaned and the garbage lifted regularly so that the place is free from mosquitoes and flies and a hygienic environment prevails.
Yours faithfully,
(Sujit Mishra)

Answer:
(a)

Plot No. 106,
Jaydev Vihar
Bhubaneswar
25 Sept., 20.

To
The District Transport Manager,
OSRTC
Cuttack
Sir,
I wish to invite your attention to the rude behavior of bus conductors on the BBSR-Cuttack route. I am a regular commuter to Cuttack as I study there. Every day I take the OSRTC Bhubaneswar-Cuttack ‘Students Special’ to Ravenshaw College. As a student I am entitled to a fifty percent concession in the fare which amounts to Rs. 3.50. But the conductor charges Rs. 4.00 every time. In spite of our repeated requests, he has been doing this regularly.

Yesterday, he stopped the bus mid-way and forced a few classmates of mine, out of the bus. He even threatened them with dire consequences if they reported him and did not pay Rs. 4.00 as fare. Moreover, he takes in passengers other than students on the bus and charges them Rs. 10.00/- for dropping them off near Ravenshaw. As a result, many bona fide students are deprived of this facility.

It is a well-known fact that this conductor is a goonda and therefore he treats the passengers with little respect and has the bus move according to his own whims and fancy with unscheduled stops and erratic timing. As a result other conductors to have become lackadaisical in their work and high-handed with passengers. I request you therefore to look into the matter and take action to transfer the conductor in question to some other zone so as to pacify and solve the problems of the students.
Yours faithfully,
Prabhat Mishra

To
The Station House Officer Cantonment Police Station Cantonment Road Cuttack Sir,
I wish to invite your attention to the disfiguring of walls in our locality. As you are aware Cuttack Chandi is graced by the Chandi temple as well as many educational institutions like the Sailabala Women’s College and Christ College. It is sad that the walls of this temple that houses the goddess and the walls of these temples of learning are disfigured by posters of films, posters advertising meetings or Tutorials, etc. Right in front of the Chandi Temple, the wall of Sailabala College provides a convenient place for posters.

But the sight of nude film posters is not only disconcerting but also ugly to look at. Similarly, the walls of Christ College have been disfigured by posters. Walls of private houses paralleling the wall of Christ College also have not been left untouched. I, therefore, request you to kindly enforce the prohibition on pasting posters on the walls of the Chandi temple as well as the colleges and private houses. The citizens’ committee is also willing to provide bamboo screens at suitable sites chosen by you, for putting up the posters.
Yours faithfully,
Santanu Mohanty

The power cuts occur so erratically and with such increasing frequency as well as for such long hours that our preparation for the examination is greatly hampered. Besides, we are not even able to sleep well so that we can appear for the Examination the following morning without feeling sleepy and tired. It would not be too far-fetched to say that the power cuts are indirectly affecting our performance in the examinations.

We are not against load-shedding but with unscheduled power cuts, we are unable to plan out when we could relax and when to give time to studies. On the other hand, if load-shedding is scheduled, even for a whole hour, we could spend that time relaxing, going on walks, and thereby refreshing our minds and body. I request you therefore to view this matter seriously and prevent unscheduled power cuts.
Yours faithfully,
Ramesh Jena

CHSE Odisha 11th Class English Writing Personal Letters and Notes

The art of Writing Letters

Letters form an integral part of inter-personal communication. There are different tyeps of letters – personal letters which may be informal or casual, business letters, letters of public concern which appear in the newspapers, etc. which are formal in nature.
The name ‘personal letter’, generally refers to letters written to friends and relations. Such letters are usually full of news, and are usually written in conversational style. It has six parts :
1. The address of the sender
2. The date
3. The salutation or greeting
4. The body of the letter
5. The subscription or complimentary close
6. The signature

CHSE Odisha Class 11 English Writing Personal Letters and Notes

Let us look at these parts one by one.

1. The Address of the sender
This is written on the top right-hand comer of the page. Look at the punctuation.
For example,

181, Saheed Nagar
Bhubaneswar.

2. The date is written below the sender’s address

8 August 20

3. The salutation
When writing to a friend, address him by name :
Dear Sarat,
Not Dear friend Sarat.
If you are writing to the parents or brothers or sisters or intimate friends, you could write
My dear Father,
My dear Mummy, etc.
The punctuation after the salutation agrees with the punctuation of the sender’s address. A comma can be placed after the salutation if you have used commas in writing your address at the top.

4. The body of the letter.
This is the most important part of the letter. A good personal letter must be simple and pleasant to read. It is full of small details which appeal to the person you are writing to. The tone of the letter must be personal: you should write as you would speak to him if he were present before you.

5. The Subscription.
The most eomon form of closing a letter to a friend is

Yours sincerely
Yours sincere friend
Yours ever, etc.

To both friends and relations you can write

Yours affectionately

Some other closng phrases that can be used in personal letters

Ever sincerely
Yours
Your loving son
Love

6. The Signature
A letter to a friend or a close relation does not require your full signature. You should write only the first name, or the name by which you are known to the friend you are writing to : not

Sarat Kumar Mohanty
but only Sarat

7. The Address on the Envelope
Usually the address is written towards the lower half of the envelop leaving space at the top for stamps. The titles, Mr, Mrs and Ms are used before the names. Sometimes postcards are used to write personal letters. Then it is not necessary to use all the six parts in the letter. The date, the message and the signature or initials of the sender will be enough.

Errors in the first letter:
(1) The addresses and names of the receiver have been wrongly placed.
(2) Address (excluding the name) and date should be written on the top in the right-hand comer.
(3) Salutation – Dear friend is wrong.
(4) Sentences in the main part are not in order.
(5) They are replete with grammatical errors.
(6) Ending is wrong.
All these errors have been corrected in the above letter.

CHSE Odisha Class 11 English Writing Personal Letters and Notes

Activity 2

The two paragraphs are given below from the body of a personal letter. Do you find anything odd about them? One part of the letter has to be rewritten in order to make it sound personal and informal. Which part is it? Identify the part and rewrite it. “I have just returned after a wonderful holiday with you. I thought I should write to you immediately and tell you how I enjoyed every minute of my stay with you. Your cousins are such jolly companions and I will never forget the fun we had together. However, I shall be failing in my duty if I do not express my profound gratitude to your parents who spared no pains to extend warm hospitality to me during my stay there.”
Answer:
The second paragraph lacks substance in the context of a personal letter which is informal, but here it is formal to the core. The ending should be ‘the hospitality of your parents has moved me. I look forward to visiting your home and staying there for some time.’

Our tour of the steel plant proved disastrous. A fire broke out in the smelting plant and we had to vacate the premises immediately. That was a horrifying experience. The whole town is full of smog, and that makes it terribly hot and sticky out here. I can’t wait to get back home.
Love,

Dear Bathsheba,
We landed here on the moon yesterday. It’s cold and eerie here with no gravitational pull. Today with my space suit on, I took a walk or rather jumped all over the moon’s surface collecting rock and soil samples. The silence is frightening.
Already feeling homesick.
Love,

Dear Roberts,
The war is getting bloodier day by day. Thousands of dead bodies lie on the battlefield, their stench filling the air. Tending to be sick and dying; almost every minute of the day is exhausting but I am glad to be of help to the soldiers.
Hoping that the war will end soon.
Cheer up.

(i) y = ex, y = 0, x = 4, x = 2
Solution:
Area = \(\int_2^4\)ex dx
= \(\left[e^x\right]_2^4\)
= e4 – e2

(ii) y = x2, y = 0, x = 1
Solution:
Area = \(\int_0^1\)x2 dx
= \(\left[\frac{x^3}{3}\right]_0^1\)
= \(\frac{1}{3}\)

CHSE Odisha Class 12 Math Solutions Chapter 10 Area Under Plane Curves Ex 10

(iii) xy = a2, y = 0, x = α, x = β (β > α > 0)
Solution:
Area = \(\int_\alpha^\beta y\)y dx

= a2\([\ln x]_\alpha^\beta\)
= a2 ln (β/α)

(iv) y = sin x, y = 0, x = \(\frac{\pi}{2}\)
Solution:
Area = \(\int_0^{\frac{\pi}{2}}\)sin x dx
= \([-\cos x]_0^{\frac{\pi}{2}}\)

Solution:
Given circle and the straight line are x2+ y2 = 4 and x+ √3y = 2
The circle has the centre at (0, 0) and radius ‘2’.
The eqn. (2) can be written as
y = –\(\frac{1}{\sqrt{3}}\)x + \(\frac{2}{\sqrt{3}}\)
Slope of the strainght line = –\(\frac{1}{\sqrt{3}}\)
The line makes and angle of 150° with x-axis making intercept \(\frac{2}{\sqrt{3}}\) from y-axis.
It intersects x-axis at (2, 0).
CHSE Odisha Class 12 Math Solutions Chapter 10 Area Under Plane Curves Ex 10 Q.4(1)
Solveing (1) and (2),
ge wet (2 – 3√y)2 + y2 = 4
4 + 3√y2 – 4√3y + y2 = 4
4y2 – 4√3y = 0
y(y – √3) = 0
y = 0 or y = √3
When y = 0, x = 2
When y = √3, x = -1
Thus the straight line intersects the circle at (2, 0) and (-1, √3).

CHSE Odisha Class 12 Math Solutions Chapter 10 Area Under Plane Curves Ex 10 Q.4(3)
⇒ x4 = 64 a4
⇒ x4 – 64 a3x = 0
⇒ x (x3 – (4a)3) = 0
⇒ x (x – 4a) (x2 + 4ax + 16a2) = 0
⇒ x = 0, 4a
When x = 0, y = 0 and
when x = 4a, y = 4a
Thus the two parabolas intersect at (0, 0) and (4a, 4a).
Area between two parabolas
CHSE Odisha Class 12 Math Solutions Chapter 10 Area Under Plane Curves Ex 10 Q.4(3.1)

(iv) Determine the area common to the parabola y2 = x and the circle x2+ y2 = 2x.
Solution:
Gien parabola is y2 = x
Given circle is
x2 + y2 = 2x ⇒ (x – 1)2 + y2 = 1
The centre is at (1, 0) and radius is 1.
CHSE Odisha Class 12 Math Solutions Chapter 10 Area Under Plane Curves Ex 10 Q.4(4)
Solving (1) and (2) we get
x2 + x = 2x ⇒ x2 – x = 0 ⇒ x(x – 1) = 0
⇒ x = 0, x = 1
When x = 0, y = 0 and when x = 1, y = 1.
Thus both the parabola and circle intersect at (0, 0) and (1, 1).
