Answer:

Jason is 14 year old.

Explanation:

Given: Joe, John and Jason are each a year apart in age.

Sum of their age is 39.

Lets assume the age of Joe be x

∴ Age of Jahn will be
(x+1)

And age of Jason will be
(x+2)

Now, putting up an equation for the sum of their age.


x+(x+1)+(x+2)= 39

Opening the parenthesis.


x+x+1+x+2= 39


3x+3= 39

Subtracting both side by 3


3x= 36

Dividing both side by 3


x= (36)/(3)


x= 12\ years

Hence, Joe is 12 year old.

Next subtituting the value of x to find age of Jason and John.

Jason=
(x+2)= 12+2

∴Jason= 14 years.

John age=
(x+1)= 12+1

∴ John Age= 13 years.

Hence, Jason is 14 year of age.
