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

Premium liability at December 31, 2020 = ((510,000*60%) - $130,000) / 8*3
Premium liability at December 31, 2020 = 176,000 / 24
Premium liability at December 31, 2020 = 7,333.33
Premium liability at December 31, 2021 = 7333.33 + ((600000*60%) - 150000) / 8*3
Premium liability at December 31, 2021 = 7333.33 + 360,000 - 150,000
Premium liability at December 31, 2021 = 217,333.33
