回複：回複：有趣的邏輯思維測試題： (9)的答案

i have a better solution
if 1x:1x:2x then no-no-yes
if 3x:1x:2x then no-no-no -yes
if 3x:5x:2x then no-no-no -no -yes
if 3x:5x:8x then no-no-no -no-no-yes

your solution is here - not as perfect as the 1st one... but seems it works to me. as i said in my earlier post - there might be muti-solutions.
if 1x:1x:2x no-no-yes
if 1x:3x:2x no-no-no no-yes
if 1x:3x:4x no-no-no no-no-yes
