The presnet ages of 3 three.
(x+y+z)/3=30 ---> eq1.
Five years ago
(y+z)/2=25
y+z=50 ---> eq.2.
Put the values of y+z in thr first equation we get:-
(x+50)/3=30,
x=90-50,
x=40.
(x+y+z)/3=30 ---> eq1.

@ALL.
Members average-years ago=average age.
((h+w+c)/3)-3=27.........=90.
n0w average age of wife and child.
((w+c)/2)-5=20............=50,
So, 90-50=40 years.
