[eggq]

請教各位高手們
An integer greater than 1 that is nor prime is called composite.
If the two-digit integer n is greater than 20, is n composite?

(1) The tens digit of n is a factor of the units digit of n.
(2) The tens digit of n is 2.

正確答案:(A)

我選(D)
請問選項(2)位啥不行呀?
或許是我題目看不懂吧

[superruby]

題目意思: 大於1且非質數的整數叫composite.
一個大於20的二位整數是composite 嗎?

2. 十位數是2 -> 23, 29 都不是composite
so Anser is A
