we represent Sharon's age by S; let Anne's age be A and Tom's age be T. In this case, the second statement is represented by A = 3 + S. The third statement is T = 5 + A. The fourth statement is represented by T + S + A = 62Solving the four equations: T = 25, S = 17, and A = 20. Hence Sharon's age is 17.
