(1)The exact numbers of 10-cent, 25-cent, and 50-cent coins among the 16 coins in the jar are, respectively, 6, 5, and 2.
(2)Among the 16 coins in the jar there are twice as many 10-cent coins as 1-cent coins.
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.
1： 能求出1cents是3枚。5cents是0枚。
2： 5cents是0枚，20cents的币是5枚，50的是2枚时，条件成立有且只有一种答案。
