Question 1196680
<br>
The difference in their ages -- now and at any other time -- is 7 years.<br>
So when Clement was 3/4 as old as Peter, their ages were 21 and 28.<br>
(If you don't see that with mental calculations, here is the algebra:
Clement's age = 3x
Peter's age = 4x
difference = x = 7
Clement = 21; Peter = 28)<br>
That was 20 years ago, so now their ages are 41 and 48.<br>
ANSWER: Clement is now 41<br>
