Answer: Sum of Age = 90
Explaination:
Let Pr be the Present Age of every individual
Raj's Age:
Raj (Pr + 4 years) = 27 years
Raj (Pr) = 23 years
Raj (Pr + 2 years) = 25 years
Raj (Pr - 4 years) = 19 years
Father's Age:
Father (Pr + 2 years) = 2 × [Raj (Pr + 2years)]
Father (Pr + 2 years) = 50 years
Father (Pr) = 48 years
Mother's Age:
Mother (Pr - 4 years) = 2 × [Raj (Pr - 4 years)]
Mother (Pr - 4 years) = 38
Mother (Pr) = 42 years
Sum [Father (Pr) + Mother (Pr)] = 48 + 42 = 90 years.
