Answer 1

✬ Arpita's Age = (3x + 9) Years ✬

Step-by-step explanation:

Given:

• Present age of Arpita is thrice of Shilpa's age.
• Age of Shilpa three years ago was x years.

To Find:

• What is the present age of Arpita ?

Solution: Let the present age or Arpita be y years.

According to the question

• Shilpa's age 3 years ago = x years

∴ Present age of Shilpa = (x + 3) years.

So present age of Arpita = y years

$\implies{\rm }$ y = Thrice of Shilpa's age

$\implies{\rm }$ y = 3 × (x + 3)

$\implies{\rm }$ y = 3x + 9

Hence, the present age of Arpita is 3x + 9 years.

Answer 2

Given:-

• Arpita's present age is thrice of Shilpa.

• Shilpa's age three years ago = x years.

To Find:-

• Arpita's present aage

Solution:-

Let Shilpa's present age be $k$ years.

According to question,

Arpita's present age is thrice of Shilpa. So, Arpita's present age will be $3k$ years.

Three years ago,

Shilpa's age = x years

Shilpa's present age = $x + 3$

• So, $x + 3 = k$

Arpita's present age $=\:3k$

⠀ ⠀ ⠀⠀⠀ ⠀ ⠀⠀⠀⠀⠀ $=\:3(x + 3)$

⠀ ⠀ ⠀⠀⠀ ⠀ ⠀⠀⠀⠀⠀ $=\:3x + 9 \:years$

Hence, Arpita's present age is 3x + 9 years.
