有兩個方法.......
(English)
Let y be the original volume of the juice.
y X16%=315
y=315 X16/100
y=50.4
Therefore the orginal volume of juice is 50.4ml.
(中文)
將原本橙汁的容量設為y
y X16%=315
y=315 X16/100
y=50.4
所以原橙汁的容量是50.4毫升。
或
Let X be the original volume of the juice
X(1-16%) = 315
X = 375 ml

Let y be the original volume of the juice.
y X(1-16%)=315
y=315 ÷84/100
y=375
Therefore the orginal volume of juice is 375ml.

將原本橙汁的容量設為y
y X16%=315
y=315 ÷ 84/100
y=375
所以原橙汁的容量是375毫升。
