Answer:
The boy: 8 years old
The sister: 11 years old
Explanation:
We assume that the age at present of the boy is x (years old).
As he is younger than his sister 3 years, so that his sister's present age is great than x 3 years
=> Her present age is: x + 3 (years old)
Two years ago, the boy is younger than present two years
=> The boy's age two years ago is: x - 2 (years old)
Similarly, the sister's age two years ago is: (x+3)-2 = x + 1 (years old)
As given, two years ago he was two-thirds of his sister's age, so that we have:
<em>The boy's age two years ago = </em>
<em> × the sister's age two years ago</em>
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
=> x + 3 = 8 + 3 = 11
So the present age of the boy is 8 years old, of the sister is 11 years old

Dear Sir,
Complaint Lodgment Over an Unexpected Error in My Bill
This is to bring to your notice an unexpected error of $9 over charge in the consumable items I purchased from your store yesterday, 13 May 2020.
From my recalculation of the total amount for the purchased item, I could observed that the error was due to a transposition of figure by your cashier; he charged me a total sum of $76 instead of $67.
Copies of the invoice and the payment receipt for the items are hereby attached to this letter for your verification. After your verification, kindly get back to me so that I can come to your office for the refund.
I look forward to receiving your usual timely response.
Yours sincerely,
Amcool.
