本人英语水平有限,恕无法用英语回答~!
这是一题数学上的比例问题.
X正比于Y,即设X=KY,则当Y上升30﹪时,X也上升30﹪,即1.3X;
且X反比于Z,即X正比于1/Z,所以设X=K·1/Z,Z下降30%,则变为(10/7)·X.
所以,两个X是不同的!Understand?
就这样了!o(-"-)o

x变化直接为Y,但成反比Z.如果y是增加了30%和Z是下降了30%,请问x不同?
X is proportional to Y, the set X = KY, when increased 30% Y, X has increased 30%, 1.3X; and X is inversely proportional to Z, that X is proportional to 1 ...

x变化直接为Y,但成反比Z.如果y是增加了30%和Z是下降了30%,请问x不同?
X is proportional to Y, the set X = KY, when increased 30% Y, X has increased 30%, 1.3X; and X is inversely proportional to Z, that X is proportional to 1 / Z, so the set X = K · 1 / Z, Z decreased by 30%, then becomes (10 / 7) · X. Therefore, both X is different!
