Three years ago, the average age of Vedh and Veehan was 18 years. When Arjit joins them, the average age becomes 22 years. How old is Arjit now?
24
Present age of (Vedh + Veehan) = (18 ×2 + 3 ×2 ) years = 42 years.
Present age of (Vedh + Veehan + Arjit) = (22 ×3 ) years = 66 years.
Therefore Arjit's age = (66 -- 42) years = 24 years.
