arithmetic - four years ago the ishanths age was three times the age of his son the total of the ages of ishanth and the son after four years will be 64 years what is the ishanths age at present - skillgun

Let the ages of Ishanth and son 4 years ago be 3x and x years respectively.
Then, [(3x+4)+4]+[(x+4)+4]=64 ‹=› 4x=48
x= 12.
Ishanth's present age 3x+4=40.
