Let the age of the man be x
Then the age of his son becomes (x−24)
2 years later from now,
The age of man will be = x+2
and age of his son will be =(x−24+2)=x−22
According to the question,
2(x−22)=x+2
i.e., 2x−44=x+2
i.e., x=46
Therefore,
The present age of man=46 years
And present age of his son = is 46−24 = 22 years
