Question
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,
SP₁ = 10000 (20% loss) ⇒ CP₁ = 10000/0.8 = 12500 SP₂ = 10000 (20% gain) ⇒ CP₂ = 10000/1.2 = 8333⅓ Total CP = 12500 + 8333⅓ = 20833⅓ Total SP = 10000 + 10000 = 20000 Loss = 20833⅓ − 20000 = 833⅓ Loss% = (833⅓ ÷ 20833⅓) × 100 = 4% loss
