please solve the problem

Answer 1

Hey There!!!


Let us assume that


Present age of son = x

Present age of father = y



We are given that Father's age is six times that of son's age. 
So, 

y = 6x   -----(1) 



Four Years Later, 
Age of Son = x+4
Age of Father = y+4 


It is given that this age of father is four times that of son. 

So we have: 


(y+4)=4 (x+4) 
=> y+4=4x+16
=> y = 4x + 12 



Let us substitute y=6x from(1)

=> 6x = 4x + 12
=> 2x = 12 
=> x = 6



Since y = 6x, we have y = 36




Thus, we have: 

Present Age of Son = x = 6 years

Present Age of Father = y = 36 years



So, Your answer is Option C.
