Answer Posted / sumit jha
when ws peter as as paul is nw?? (x-y) years ago!!
so those years ago paul's age= y-(x-y) yrs
now qstn says peter is twice the age as paul ws then.
so x/2 = y-(x-y)
or x/2=2y-x
or x= 4y - 2x
or 3x = 4y
or y = 3/4x
rplacing d value of y in d equation x+y=35 we get answer as
-----
x=20
-----
y =15.
------
thus (x-y)=5 yrs ago y was 10 and x is twice that=20.
but x+y=35
