[quote=Anonymous]You cannot uniquely determine this. Let: A = % submitted SAT only B =% submitted ACT only C = % submitted both D = % submitted neither So A+B+C+D=100. Also, A+C=47 and B+C=30. You have three equations but four unknowns. Undetermined. You can however determine the smallest and largest possible D. The largest D is 53 which is achieved when A=17, B=0, C=30. The smallest D is 23 which is achieved when A=47, B=30, C=0. So the % that went TO is between 23% and 53%.[/quote]
