Q4:
What is the hundreds digit of the integer z?
(1) 10z = 93,120
(2) z rounded to the nearest hundred is 9,300.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
请问(2) z rounded to the nearest hundred is 9,300.是什么意思啊?把Z四舍五入到9300的百位?比如说9304四舍五入到百位就变成饿9300,9295变成9300,是这个意思吗?好奇怪啊~~~麻烦哪位XDJM给我这笨脑袋点拨一下~~ |
