Arpitas present age is thrice of shilpa. If shilpas age $$3yr$$ ago was $$x$$. Then, Arpitas present age is

• A

  $$3(x-2)$$

• B

  $$3x+9$$

• C

  $$3x-9$$

• D

  $$3(x)$$

 Given that:

Shilpa's age $$3$$ years ago is $$x$$ years. 

Therefore, 

Present age of shilpa is $$(x+3)$$

 Arpita's present age is thrice of shilpa. Therefore Arpita's present age is 

$$3(x+3)$$$$=$$$$3x+9$$ years 

Arpita's present age is thrice of Shilpa. If Shilpa's age three years ago was x, then Arpita's present age is
