✔ 最佳答案
192-(144-y+1.5y) = 32/3% * 192 /(100%)
192-144-0.5y = 20.48
-0.5y = -27.52
y = 55.04

192 - (144 - y + y X 1.5)       2
----------- X 100% = 16 ---- %
192                3
192 - (144 - y + y X 1.5)  50
----------- = ----
192            3
3(192 - 144 + y - 1.5y) = 50*192
576 - 432 - 1.5y = 9600
144 - 1.5y = 9600
-1.5y = 9600 - 144
y = -6304
