A) 35
B) 10
C) 20
D) 15
Correct Answer: D
Solution :
Let the age of Renu \[=x\,yr\] and age of Renu's mother \[=y\,yr\] \[(y-5)=2(x-5)\] \[\Rightarrow \] \[y-5=3x-15\] \[\Rightarrow \] \[y-3x=-10\] ?(i) and \[(y+5)=2(x+5)\] \[\Rightarrow \] \[y+5=2x+10\] \[\Rightarrow \] \[y-2x=5\] ?(ii) On solving Eqs. (i) and (ii), we get \[x=15,\] \[y=35\] \[\therefore \] Renu's present age \[=15\,yr\]You need to login to perform this action.
