Let the present age of Virat be x years

His age 7 years ago = x - 7 years

His age 7 years later = x + 7 years

According to the given condition, (x - 7) (x + 7) = 480

 x^{2}  +7x - 7x - 49 = 480

 x^{2}  - 49 = 480

 x^{2}  = 480 + 49

 x^{2}  = 529

⇒ x = \sqrt{529}

⇒ x = 23

Hence the present age of Virat is 23 years.
