Solution :
Let the son's present age \[=x\]years. \[\therefore \]Father's present age \[=3x\]years After 15 years, \[3x+15=2(x+15)\] \[\Rightarrow \] \[3x+15=2x+30\] \[\Rightarrow \] \[x=30-15=15\] \[\therefore \]Sum of their present ages \[=x+3x=4x\] \[=4\times 15=60\] yearsYou need to login to perform this action.
