Answer: Let the number of family members be 'x'
the average age of the family members 5 years ago is 25 years
so the sum of age of all family members 5 years ago = 25 into x = 25x
the sum of age of these family members now and after 5 years elapsed = 25 x (these added 5 years * no of family members) = 25x + 5x = 30x
Sum of ages = 30x
no. family members = x
Therefore, current, average age = sum of ages/ no. of members = 30x / x = 30
