Subject: Pollution and its impact on environment.
Sir:
I am writing this letter to you to express my deep concern over the problem of pollution in our city, which is affecting the environment drastically. As you already know ours is an industrial city. The dying mills release at least 300 million liters of waste water into the Sutlej River on daily basis. This waste water contains harmful chemicals like arsenic, cadmium, mercury, and chrome. These chemicals have already killed the aquatic life.
Moreover the smoke arising from the factory chimneys has polluted the air badly. I want to draw the attention of the people as well as the concerned authorities to the seriousness of the problem. The mills and factory owners are violating the environmental laws by not treating the waste water and the smoke before releasing it into the environment. The corrupt environment officers are letting it happen just because of the hush-money they receive from the culprit owners.
But we the residents are suffering. The environment authorities responsible for preserving the environment must ensure the mills and factories owners follow the environmental protection rules and regulations by properly treating effluents and the toxic smoke in the pollution treatment plants before releasing them into the environment.
Through the medium of your esteemed daily I appeal to the public to raise their voice against these unethical practices. I also appeal the environment ministry to look into the matter and take immediate action against the law breakers. I appeal to people to come forward to save our environment from the curse called pollution; these ministers and Government officials will not do anything promptly. By the time they take action, the situation will go out of hand. I am hopeful my views will find suitable place in the esteemed columns of your reputed daily.
Thanking you.
Yours truly,hope it helps

B) We need to find the sum of all the numbers less than 1000, which are neither divisible by 5 nor by 12.
Numbers divisible by 2 upto 1000 are 2, 4 , 6, ........ 1000.
Sum of all the numbers divisible by 2 upto 1000 = 2 + 4 + 6 + ....... + 1000 = 2 (1 + 2 + 3 + .......... + 500)
[Using: sum of first n natural numbers]
Numbers divisible by 5 upto 1000 are 5, 10 , 15, ........ 1000.
Sum of all the numbers divisible by 5 upto 1000 = 5 + 10 + 15 + ....... + 1000 = 5 (1 + 2 + 3 + ........ + 200)
Let us find out the sum of all the numbers which are divisible by both 5 and 2.
Numbers divisible by both 2 and 5 will be divisible by 10.
The numbers upto 1000 which are divisible by 10 are: 10, 20, 30, 40, ............ 990, 1000.
Clearly, this forms an AP with a = 10, d = 10, an = 1000, where n can be found out as follows:
an = a + (n – 1) d
⇒ 1000 = 10 + (n – 1) × 10
⇒n = 100
Sum of all the numbers upto 1000 = 1 + 2 + 3 + ........... + 999 + 1000
Sum of all the numbers less than 1000, which are neither divisible by 5 nor by 2 =
Sum of all the numbers upto 1000 – (Sum of all the numbers divisible by 2 upto 1000 + Sum of all the numbers divisible by 5 upto 1000 – Sum of all the numbers which are divisible by both 2 and 5)
= 500500 – (250500 + 100500 – 50500)
= 200000
c) Pressure groups and movements exert influence on politics in a variety of ways.
They try to gain public support and sympathy for their cause by carrying out information campaigns, organising meetings, filing petitions, etc.
By organising strikes and disruptions, they seek to make the government take note of their demands.
They also influence decision-making by lobbying.
The issues raised by them often influence the policies of political parties.
