Let initial age of son be x.
Initial age of father = 3x + 3                  -----1
After 3 years, age of son = x+3
Age of father after 3 years = 2(x+3) + 13  -----2
From 1 and 2,
3x + 3 +3 = 2(x+3) + 13
3x + 6 = 2x + 19
x = 13
So, Father's initial age = 3x + 3 = 42
Age of son after 4 years = 13 + 4 = 17
Age of father after 4 years = 42 + 4 = 46
