CHAIR
original price $500
new price $500 x (1-30%) = $350
TABLE
original price $750
new price $750 x (1+24%) = $930
TOTAL MONEY
original 500+750 = 1250
new 350+930 = 1280
Profit in % = (1280 - 1250) / 1250 = 2.4%
therefore, (ying)利百分率=2.4%

help u no problem. but afraid misunderstand your question.
X蝕 = loss? (ying)利 = profit?
if yes, then...
Chair = $500 x (1-30%) = $500 x 70% = $350
Table = $750 x (1+24%) = $750 x 124% = $930
$$ he spends to buy the chair and table = $500 + $750 = $1250 (成本)
$$ he earns to sell the chair and table = $350 + $930 = $1280
That's why he earns = $1280 - $1250 = +$30
profit % = $30 / $1250 = +2.4%
X蝕 = loss? (ying)利 = profit?
if yes, then...
Chair = $500 x (1-30%) = $500 x 70% = $350
Table = $750 x (1+24%) = $750 x 124% = $930
$$ he spends to buy the chair and table = $500 + $750 = $1250 (成本)
$$ he earns to sell the chair and table = $350 + $930 = $1280
That's why he earns = $1280 - $1250 = +$30
profit % = $30 / $1250 = +2.4%
