Answer 1

Man's age = 40
Sons's age = 14 
Let 
Number of years = x 
father will be = 40 + x
Son will be = 14 + x 
Twice the age of son after x years = father's age after x years
2(14+x)=40+x


28+2x=40+x
2x-x=40-28
x=12 

After 12 years father will be twice as old as his son. 
Check
======
Man's age = 40 +12 = 52 (which is twice of 26)
Sons's age = 14 + 12 = 26

Answer 2

Let the age of father will be twice as old as his son after 'x' years.

Age of man = 40 + x.

Age of Son = 14 + x.

Now,

= > 40 + x = 2(14 + x)

= > 40 + x = 28 + 2x

= > 40 - 28 = x

= > x = 12.

Now,

Age of man after 12 years = 40 + 12 = 52 years.

Age of man after 12 years = 14 + 12 = 26 years.
