Explanation:

According to the the question:
A : B = 4 : 5
A : C = 8 : 9
So,
A : B : C = 8 : 10 : 9
Let the present ages of A, B and C be 8X, 10X and 9X respectively.
The difference between the age of A and C is 5 years.
9X - 8X = 5
X = 5
Then the sum of the ages of A, B and C
after 11 years.
(A + 11) + (B + 11) + (C + 11)
(8 × 5 + 11) + (10 × 5 + 11) + (9 × 5 + 11)
51 + 61 + 56 = 168
