The present age of John is 3 years

The present age of Annie is 5 years

Given that John is 2 years younger than Annie's age

Let the present age of John be "J"

Let the present age of Annie be "A"

According to the given situation

[tex]\rm J = A -2........(1)\\[/tex]

One year ago the age of John = [tex]\rm J-1[/tex]

One year ago the age of Annie = [tex]\rm A -1[/tex]

According to the given situation

[tex]\rm\dfrac{A-1}{2}= J-1.........(2)[/tex]

On solving for equations (1) and (2) we get

A = 5 and J = 3

So the present age of Annie is 5 years

The present age of John is 3 Years
