let present age of pramod is X yrs. and of Ravi is Y yrs.
8 yrs ago, pramod age =(X-8)yrs.
8 years ago Ravi age =(Y-8)yrs
a/q,(Y-8)=3/4(X-8)
on solving it we get,
4y-32=3x-24
3x-4y=-8..................(I)
now 4 yrs hence pramod age =(X+4)
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,Ravi age =(Y+4)
a/q,(Y+4)=6/7(X+4)
on solving it we get, 7y+28=6x+24
6x-7y=4......................(ii)
on solving i and ii we get Y=20 and X=24
present age of Ravi is 20years and of pramod is 24 years
