請試找出以下字母所代表的數值。

A x A=100
B + B + C= E
C + D= E
A +  A + A =B + B
D - A=C


小言也是想了很久才想出答案,大家動動腦試試吧~

如果所有都係正數:

A x A = 100 --> A = 10
A + A + A = 30 = B + B --> B = 15

B + B + C = E --> 30 + C = E (1)
C + D = E (2)
(1) = (2) --> B + B + C = E = C + D
--> 30 + C = C + D
--> D =30

D - A = 30 - 10 = 20 --> C = 20
C + D = E --> E = 20 + 30 = 50

A = 10
B = 15
C = 20
D = 30
E = 50

答中啦~
sss以前有玩過這個嗎!?

沒有啊!
不過其實都是加加減減,
都係咁計出來啦!!
