Answer Posted / paul
The answer is 21 years old (age of Peter).
Equation:
let x = present age of Peter
y = present age of Paul
When Peter has the same age as Paul (y yrs. old), age of
Paul is y/2 yrs. old. Since the differences of there ages
are equal for the 2 events, we have the equation...
x - y = y - y/2
y = (2/3)x
Substituting the equation of y to the equation x + y = 35,
will give us....
x + (2/3)x = 35
therefore, x = 21 (age of Peter)
