A) \[60,\,\,30\]
B) \[30,\,\,60\]
C) \[40,\,\,50\]
D) \[50,\,\,40\]
Correct Answer: A
Solution :
Let the present ages of A and B be \[2x\] years and x years. After 30 years, their ages will be \[A=(2x+30)\] years \[B=(x+30)\] years So, \[2x+30=1\frac{1}{2}(x+30)\] \[\Rightarrow \] \[x=30\] \[\therefore \]Present age of \[B=30\]years \[\Rightarrow \] Present age of \[~A=2\times 30=60\] yearsYou need to login to perform this action.
