20 years ago, Antony’s age was 1/2 of what his age now

20 years ago, Antony’s age was 1/2 of what his age now is. What is his age now?

Suppose the present age of Antony is P years.

20 years ago his age was	P	years
	2

According to question ,

the present age of Antony - 20 years =	the present age of Antony
	2

⇒ P - 20 =	P
	2

⇒ 2P – 40 = P
⇒ 2P – P = 40
∴ P = 40 years
Hence , the present age of Antony is 40 years.
