Is the integer k divisible by 4 ?
(1) 8k is divisible by 16.
(2) 9k is divisible by 12.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
条件1只能说明K可以被2整除无法说明可以被4整除。条件2化简得3k/4-----k/4可以被整除
条件2化简得到3k是4的倍数,因为3k的3是质数,不包含4,所以3k如果要是4的倍数,K一定是4的倍数。
