Let's denote the present age of the elder person as E and the present age of the younger person as Y.

From the problem, we know that:

1) E = Y + 20 (since their ages differ by 20 years)

2) E - 5 = 5 * (Y - 5) (since 5 years ago, the elder one was 5 times as old as the younger one)

We can substitute E from the first equation into the second equation to solve for Y:

(Y + 20) - 5 = 5 * (Y - 5)

Solving this equation gives Y = 10.

Substituting Y = 10 into the first equation gives E = 10 + 20 = 30.

So, the present ages of the elder and younger person are 30 and 10 years, respectively.
