问题 Each symbol in this table has a value. The total of these values in each row and column is written at the end of the corresponding row or column. Can you find the value of each symbol?
选项 A、Triangle = 6.5, Square = 4.2, Diamond = 5.8, Circle = 11.4
B、Triangle = 7.5, Square = 5.2, Diamond = 6.8, Circle = 12.4
C、Triangle = 8.5, Square = 5.2, Diamond = 6.8, Circle = 13.4
D、Triangle = 5.5, Square = 3.2, Diamond = 4.8, Circle = 10.4
答案A
解析 可以以菱形作为突破点。分别设三角形=A，方形=B，圆形=C，菱形=D，2B+A+D=20.7，2B+C+A=26.3，将后两个等式相减可得出C-D=5.6，而通过图形可知3D+C=28.8，将这两个等式相减得出菱形C=5.8，因此A选项正确。
