The first AMC 8was given in 1985and it has been given annually since that time. Samantha turned 12 years old the year that she took the seventh AMC 8. In what year was Samantha born?
If you say she was born in 1979 = (1991-12) , it means she will be 1 year old in 1980 & 12 year in 1992 ( 1 year more than AMC 7), so she was born in 1978 & she was 1 year old in 1979 + 12 = 1191
