Open in App
Solution

Let the present age of the son be x years.

Age of the mother = (x + 25) years

After 8 years,
Age of son = (x + 8) years
Age of mother = (x + 25+ 8) years
= (x + 33) years

From the given information,
x+8x+33=499x+8=4x+339x+72=4x+1329x-4x=132-725x=60x=12

Hence, the present age of the son is 12 years.
