Let the son present age = x
Let the mother present age=y
Therefore presently 4x=y……….(1)
After 6 years the equation becomes
14(x+6)=5(y+6)
14x+84=5y+30
5y-14x=54………….(2)
Subtituting eqn 1 in equation 2 we have
5(4x) - 14x =54
20x - 14x = 54
6x=54
x=9
From equation 1, 4x = y
Therefore 4(9) = y =36
Son's present age is 9years
Mother's present age is 36years
