A mother is 21 years older than her 5 years son.
After how many years the son will be 1/3 of his mother

Let y = no. of years for this to be true
:
y + 5 = (y+26)
Multiply both sides by 3
3(y+5) = y + 26
3y + 15 = y + 26
3y - y = 26 - 15
2y = 11
y =
y = 5.5 yrs, these problems usually have integer solutions, but there it is!
