07 08 09 10 11
16 15 14 13 12
17 18 19 20 21
26 25 24 23 22
27 28 29 30 31

The figure above consists of 25 squares. If the figure were folded along the dotted diagonal to form a flat triangle, then 26 minus the number in the square that would coincide with the square containing 26 would be___

The dotted diagonal是从07经15,19,23至31。想请教各位的是:”…the number in the square that would coincide with the square containing 26”指的是不是10呢?因为没有答案,所以恼人的很?谢谢!

应该是10吧。就是隔对角线对称的点,10或28。
