A merchant sold two refrigerators for 10,000 each. On
one refrigerator, he incurred a 20% loss, and on the other, he gained 20%. What was his profit/loss percentage on the whole transaction?Solution
ATQ,
SPβ = 10000 (20% loss) β CPβ = 10000/0.8 = 12500 SPβ = 10000 (20% gain) β CPβ = 10000/1.2 = 8333β Total CP = 12500 + 8333β = 20833β Total SP = 10000 + 10000 = 20000 Loss = 20833β β 20000 = 833β Loss% = (833β Γ· 20833β ) Γ 100 = 4% loss
