Answer:

the 34 yrs Is wrong it will be 4yrs only.

Step-by-step explanation:

Let my present age=x years

After 12 years my age=x+12 years

4 years ago my age =x−4 years

According to the question,

x+12=3(x−4)

⇒x+12=3x−12

⇒3x−x=12+12

⇒2x=24

or x= 24/2 =12 years.

∴ my present age is 12 years.

hope this helps you.

Let the present age of let’s say todd be X

Todd’s age (x+12) will be 3 times as old as he was 4 years ago [3(x-4)]

i.e



x+12=3(x-4)
x+12=3x-12

2x=24
X=12.
Hence Todd’s present age is 12.
