Subject: Request for replacement of damaged laptop (Order #88392)
Sir,
I am writing to bring to your notice a defect in the Asus Zenbook laptop that I purchased from your store on June 18, 2026. Upon unboxing the device yesterday, I discovered that the screen was cracked and the keyboard backlight failed to turn on.
Since the laptop is under a one-year warranty, I request you to kindly arrange for a replacement at the earliest. I have attached a copy of the receipt and photos of the damage for your reference.
Thank you.
Yours faithfully,

Subject: Need for urgent municipal action against dumping plastic waste in River Ganga
Sir,
Through the columns of your esteemed newspaper, I wish to draw the attention of the civic authorities towards the alarming level of plastic pollution polluting the banks of River Ganga in Kanpur.
Every day, heaps of non-biodegradable polythene bags, single-use bottles, and industrial effluents are dumped directly into the river. This not only chokes aquatic life but also poses severe health hazards to nearby residents who rely on the river water.
I urge the Municipal Corporation to install trash barriers, levy strict fines on polluters, and initiate clean-up drives immediately.
Yours sincerely,
Alok Kumar

Dear Varun,
I received Mom’s letter yesterday and came to know that you are feeling anxious about your upcoming Class 10 Board Examinations. I understand how overwhelming it feels, but I want to reassure you that you are well-prepared.
First, make a daily study timetable that allocates short breaks between sessions. Avoid late-night cramming, as adequate sleep is crucial for memory retention. Exercise for at least thirty minutes daily to clear your mind.
Believe in your hard work. Call me whenever you feel stressed.
Your loving brother,
Aman
Warm personal greeting to family.
