A) 33 y
B) 39 yr
C) 45 yr
D) 40 yr
Correct Answer: A
Solution :
Let the son's present age \[=x\,yr\] \[\therefore \] Father's age \[=(3x+3)yr\] After 3 yr, \[\Rightarrow \] \[(3x+3)+3=2(x+3)+10\] \[\Rightarrow \] \[36+6=2x+16\] \[\Rightarrow \] \[x=10\] \[\therefore \] Father's present age \[=3x+3\] \[=3\times 10+3=33\,\,yr\]You need to login to perform this action.
