Answer 2

Answer:

Let us assume the age of the Soni is x years.

We need to find the three fourth of Soni's age. So, we multiply x with 34 to get the four-fifth of the age of Soni.

So, the three fourth of Soni’s age is 34x years. Now, we need to add 6 years to 34x years in order to get the age 6 years older than the four-fifth of her age. So, this makes us get the age as 34x+6 years.

But this is equal to the age of his brother which is 30 years.

So, we have 3/4x+6=30

⇒3/4x=32−8.

⇒3/4x=24.

⇒x=4

⇒x=40years, which is the age of Soni.

So, we have found Soni’s age is 40 years.

• ∴ The age of Soni is 40 years.
