So I took it to be real school: Their ages could be: 1,1, and 24 <--ruled out, eldest too old to start school. 1,2, and 12 <--ruled out, eldest too old to start school. 1,3, and 8 <--ruled out, eldest too old to start school. 1,4, and 6 <--possible, kids usually start school at 6. 2,2, and 6 <--possible, kids usually start school at 6. Nothing says the younger two can't be twins. 2,3, and 4 <--ruled out, eldest too young to start school. So there are two possible answers. 1,4 and 6 and 2,2,and 6. Edwin
