Arun is celebrating his birthday today. In his next birthday, he will be twice his age that was 12 years ago. How old is Arun today? Correct Answer 25 years

Let the age of Arun is X.

12 year ago age of Arun is X - 12.

According to the question age of Arun will be twice of his age that was 12 year ago.

X + 1 = 2 × (X - 12)

X + 1 = 2X - 24

2X - X = 24 + 1

X = 25

Hence, Arun is 25 year old.
