A) 47 yr
B) 35 yr
C) 45 yr
D) 24 yr
Correct Answer: C
Solution :
Let the age of \[X=x\text{ }yr\] and age of \[Y=y\text{ }yr\] \[\therefore \] \[(x-3)=2(y-3)\] \[\Rightarrow \] \[x-3=2y-6\] \[\Rightarrow \] \[x-2y=-\,3\] ?(i) and \[x+7+y+7=83\] \[\Rightarrow \] \[x+y=69\] ?(ii) On solving Eqs. (i) and (ii), we get \[x=45,\] \[y=24\]You need to login to perform this action.
