Answer 2

Answer:

Let the present age of son be x year

the present age of mother be ( x + 25 ) years

After 8 years of son = (x + 8) years

After 8 years of mother = ( x + 25 + 8 ) = (x+

33 ) years

Ala

(x +8)/(x+ 33 ) = 4/9

=> 9 (x 8y) = 4 (x 33) =

=> 9x + 72 = 4x + 132

=> 9x - 4x = 132 - 72 =

=> 5x = 60

=> x = 60/5

=> x = 12 years

Present age of son = x = 12 years

Present age of mother = ( x + 25 ) = 12 + 25 =

37 years
