Answer Posted / shona
peter paul
present age X Y
whenPeter was Y Z
as old as Paul is now
(suppose before n years)
Peter(X) is twice(2) as old as Paul(Z) was when Peter(Y) was
as old as Paul(Y) is now => X=2Z
=>X-u=Y & Y-u=Z
i.e 2Z-u=Y u=Y-Z........(2)
u=2Z-y.....(1)
equating 1 & 2
2Z-Y=Y-Z
3Z=2Y
Z=2Y/3..........(3)
given
sum of their ages is 42
i.e
X+Y=42
2Z+Y=42
substituting from (3)
2*(2Y/3)+Y=42
7Y/3=42
Y=42*3/7
Y=18
so X=24
=> peter's age is 24
