Detailed Solution

Suppose that the age of Mohit's son =x
According to the question
Mohit's son age before 2 years age =x-2
Current age of Mohit =3(x-2)
Current age of Mohit =3(x-2)+2
=3x-6+2
=3x-4 So, Mohit's age after 2 year =(3x-4)+2
Hence son's age after 2 year =x+2
Thus, again by the given condition,
5x+2=23x-2
x=14  Current age of Mohit's son =14 years 
Mohit Age =38 years 
Option 1 is Correct.
