ATQ,
The ratio of A and B's ages after 8 years is 4:5, so we get the equation 5(A+8)=4(B+8), which simplifies to 5A−4B=−8. The ratio of A and C's ages 6 years ago is 3:4, giving us the equation 4(A−6)=3(C−6), which simplifies to 4A−3C=6. The average age of A and C is 30, so A+C=60. Solving the system of equations, we substitute A = 60 − C into the second equation and solve to get C=33.43. Thus, the present age of C is approximately 33.43 years.
