Here, let the age of student be x and teacher be 4x after 28 years, the teacher is double the age of student. So the age of teacher will be 4x+28 and student will be 2(x+28) So, 4x+28=2(x+28) 4x+28=2x+56 4x-2x=56-28 2x=28 x=14 Therefore the age of the teacher in present will be =4x+28 =4*14+28 =84 And age of student will be: =x+28 =14+28 =42 Hope this helps
