Answer: Arun = 14 years; Father = 42 years
=========================================================
Work Shown:
x = Arun's age
3x = Father's age
Note the jump from x to 3x is "times 3"
Their ages sum to 56
x+3x = 56
4x = 56
x = 56/4
x = 14
Arun is currently 14 years old and the father is 3x = 3*14 = 42 years of age.
Check: 14+42 = 56 to confirm the answer.
