Hello I need help in this problem...

A certain (3,8) threshold scheme is constructed over the integers mod 101. The shares are (1,3), (2,51), (3,76), (4,79), (5,57), (6,13), (7,47) and (8,58). Exactly obe of these shares is defective (that is, its wrong). Our job is to determine which share is defective, give its correct value and find out the value of the secret.

Thanks aot in advance!
