A Correct answer
Explanation

Five years ago, average age of Prakash and Ajay was 15, so their total age was 30. Currently, their total age is 30+10 = 40 (adding 5 years each). Present average of Prakash, Ajay, and Ramesh is 30, so their total age is 90. Therefore, Ramesh's present age = 90-40 = 50. After 10 years, Ramesh's age = 50+10 = 60 years.
