D) 30 yr
Correct Answer: D
Solution :
Let the present age of son \[=x\,yr\] And die present age of father \[=y\,yr\] By given condition, \[(y+6)=3(x+6)\] \[\Rightarrow \] \[3x-y=-12\] ?(i) and \[y-3=9(x-3)\] \[\Rightarrow \] \[9x-y=24\] ?(ii) On solving Eqs. (i) and (ii), we get \[x=6\,yr\] and \[y=30\,yr\] Then, the present age of father is 30.You need to login to perform this action.
