B is eight years older than A and 8 years younger than C. 12 years hence, respective ratio of the ages of A and C will be 5:9. what is the sum of present ages of A, B and C?
B = A + 8
B = C – 8
C – 8 = A + 8
C – A = 16
4x = 16
x = 4
12 years hence, A = 5x, C = 9x B = A + C => A= 20, B = 28, C = 36
Sum of present ages of A, B and C = 20 + 28 + 36 – 36 = 48 years.
