Aditya is 45 years older than his son Atul. If you find similarities between their ages, both of their ages contains prime numbers as the digits. Also, Aditya age is the reverse of Atul age.

Can you find their ages ?

72,27

2, 3, 5 and 7 are the only single digit prime numbers.
Now we can list the possible combinations of age:
Aditya = 32, Atul = 23
Aditya = 52, Atul = 25
Aditya = 72, Atul = 27

Now, the third one meets our requirement.
72 - 27 = 45

Thus Aditya is 72 years old and his son is 27 years old.
