• A. $3\left(\mathrm{x}-3\right)$
• B. $3\mathrm{x}+3$

• D. $3\left(\mathrm{x}+3\right)$

Answer 1

The correct option is D

$3\left(\mathrm{x}+3\right)$

Explanation for correct answer.

Given : Shilpa’s age three years ago$=\mathrm{x}$

$\therefore$ Shilpa’s present age $=\mathrm{x}+3$

NOw, Arpita’s present age is thrice of the present age of Shilpa.

$\therefore$ Arpita's present age$=3\times \mathrm{present}\mathrm{age}\mathrm{of}\mathrm{Shilpa}$

$=3\left(\mathrm{x}+3\right)$

Therefore, (D) is the correct answer.
