A) 6 yr
B) 7 yr
C) 8 yr
D) 12 yr
Correct Answer: D
Solution :
Let Sunita's present age be x yr. Then, Reena's present age = 2x yr. Three years ago, Sunita's age \[=(x-3)yr\] and Reena's age \[=(2x-3)yr.\] So, \[(2x-3)=3(x-3)\] \[\Leftrightarrow \] \[2x-3=3x-9\] \[\Leftrightarrow \] \[x=6\] \[\therefore \] Reena's present age \[=2x=12\,yr\]You need to login to perform this action.
