Answer: The present age of Deepak is 42 years.

Step-by-step explanation:

Let the age of Arun seven years ago be 5x

Let the age of Deepak seven years ago be 7x

After 7 years,

Present age of Arun would be 5x-7

Present age of Deepak would be 7x-7

According to question, the difference between the present age of Arun and Deepak is 14 years.

So, it becomes,

7x-7-(5x-7)=14\\\\7x-7-5x+7=14\\\\2x=14\\\\x=\dfrac{14}{2}\\\\x=7\ years

Hence, the present age of Deepak would be

7x-7\\\\=7\times 7-7\\\\=49-7\\\\=42\ years
