✔ 最佳答案
椅子的出售價錢=$500x(1 - 30%)
=$500 x 70%
=$350
桌子出售的價錢
=$750x(1+24%)
=$750 x 124%
=$930
原來買回來的價值 = $(500+750)=$1250
售出去的價格 = $(350+930)=$1280
因此他在整宗買賣的盈利百分率:
=$(1280 - 1250) / 1250 x 100%
=2.4%

椅子:
買價:500
虧蝕價:500x30%=500x0.3=150
售價:500-150=350 or 500x(1-30%)=350
桌子:
買價:750
虧蝕價:750x24%=750x0.24=180
售價:750+180=930 or 750x(1+24%)=930
當兩件貸為一件來計,
盈利/虧蝕率=[(新價-舊價)除舊價]x100%=[(350+930)-(500+750)]除(500+750)x100%=2.4%
即盈利率為2.4%
買價:500
虧蝕價:500x30%=500x0.3=150
售價:500-150=350 or 500x(1-30%)=350
桌子:
買價:750
虧蝕價:750x24%=750x0.24=180
售價:750+180=930 or 750x(1+24%)=930
當兩件貸為一件來計,
盈利/虧蝕率=[(新價-舊價)除舊價]x100%=[(350+930)-(500+750)]除(500+750)x100%=2.4%
即盈利率為2.4%
參考: f.5,,,雖然數學唔係好好,,應該岩既^^

椅子的售價
= $500x(1-30%)
= $500x70%
= $350
桌子的售價
= $750x(1+24%)
= $750x124%
= $930
整宗買賣的盈利百分率
= (350+930) - (500+750) / (500+750) x 100%
= 30/1250 x 100%
= 2.4%
希望幫到你la~~
